When poosh comes to shove, Kourtney Kardashian will stand up for herself.

The Kardashians star recently clapped back at an Instagram user who criticized her fashion tastes. "So not Kourtney!" the person commented on the star's March 9 post. "She use to be so classy! Wonder what her family thinks of her new style?"

But instead of pondering just how her loved ones feel about her fashion evolution, Kourtney cheekily fired back, "Ooooh inquiring minds would like to know this is so fascinating."

So what exactly sparked the criticism? The Poosh founder shared a carousel of random moments from her life, including visiting an art museum in a rocker-chic look, taking a selfie with her 8-year-old son Reign Disick as they debuted their new blonde hair transformations and showcasing her custom coat with the title "Mrs. Barker" emblazoned on the back.

Kourtney's slick comeback has seemingly become second nature to her, as she's shut down trolls in her comments section before.

This includes addressing an Instagram user who speculated on a March 2 post that the reality star and husband Travis Barker were expecting. And while Kourtney rarely feeds into the pregnancy rumors, she felt it was necessary to educate her followers about her experience with in-vitro fertilization. 

"The after affects [sic] of IVF," she wrote on Instagram, commenting on a photo of herself modeling for her brand's new supplements. "I only acknowledge this comment because I do think it's important to know how IVF affects women's bodies and it's not spoken about much. Also are we still asking women if they're pregnant?"

Back in October, she offered more insight about her IVF journey, saying that the experience "really took a toll on my health and mentally."

"The hormones. The medication. You have to get put to sleep every time," she explained on the Not Skinny But Not Fat podcast. "I know it's for so many people but it's just not for me."

Kourtney—who is also mom to son Mason Disick and daughter Penelope Disick—admitted to feeling pressured to take this route. She noted, "If you look online, it says if you're over 40, go right away to an IVF doctor. So I felt a little bit pushed."

And while IVF may have not been the 43-year-old's cup of tea, she believes everything happens for a reason.

"I got to a place where I just felt exactly like how timing is everything with me and Travis," she shared. "So, I feel like if it's truly meant to be it will happen. We are, for now, done with IVF. We say prayers and hope that god blesses us with a baby."

Of course, this isn't the first time Kourtney or the rest of her Kardashian-Jenner family have reacted to social media critics. Keep reading to see all of their epic clap backs below.

Kourtney Kardashian took a moment to tell followers exactly how she deals with negativity—blocking them. 

"Taking a minute after a peaceful pilates session to drink my tea and block some negative accounts..." Kourtney wrote alongside a peace sign emoji on her July 16 Instagram Story. "Positive vibrations bye bye to the rest."

Taking to Twitter on Aug. 28, the fashion mogul shut down false stories circulating about her. "HA! some of y'all really just make up anything and swear it's the truth as if you know what's going on," she posted. "The truth is never good enough… or juicy enough. So you create a narrative that fits what you choose to believe."

She added, "It is so old at this point. It's always something about people creating fake s--t about me and actually terrorizing me about something THEY ARE CREATING. Without anyone knowing any facts. It's some weirdo s--t."

On Aug. 27, the reality TV star called out online haters with a cheeky social media post. "Be careful outside," she wrote. "It's raining shady bitches everywhere!!" 

The Good American founder shut down an Instagram critic, who wrote, "If insecurity was a person."

"Baby girl, you have to look in the mirror," the reality TV personality responded. "Only insecure people tear other people down. I'm sending you so much love, health and happiness! I'm sorry that you're hurting."

KoKo's haters were at it again when one Instagram user commented "money spent well" on a series of glamorous snapshots she shared. 

But when the trolls go low, Khloe goes high, writing back with several laughing emojis, "the shade of it all." 

Khloe's definitely been known to switch up her look every now and then. As part of her latest transformation, she went from long-haired to short-haired and blonde to brunette. 

But when Khloe debuted the new hairstyle on Instagram, one commenter was eager to point out they somehow couldn't recognize the Good American mogul, writing, "Who is that on the right?" 

"your new step mother," Khloe hilariously responded. "Be nice or get grounded."

Kindness is key! A snapshot from a family trip captioned "lake ya" drew the following comment, "why can't you donate more money or your time to help people of the world ?"

Kourtney's response was nothing short of gracious. She replied, "always wanting to help more, do you have suggestions? Let's encourage each other, ways others can help too. As humans sharing this planet, I find it our duty to help each other."

Loving her body.

After Kourtney posted a leisurely photo of herself reading in a bathing suit, some speculated that she was pregnant. Understandably, the mother of three shut this speculation down.

"This is me when I have a few extra pounds on, and I actually love it. I have given birth three amazing times and this is the shape of my body," Kourtney clarified.

The Good American mogul took to Twitter in May 2020 after rumors circulated that she and Tristan Thompson were expecting a second child together.

"I don't go on social platforms much these days AND this is one of the main reasons as to why I stay away. The sick and hurtful things people say. I am disgusted by so many things I am seeing," Khloe tweeted. "SMH people swear they know everything about me. Including my uterus. Sick."

"The nasty things you're saying about me over A RUMOR!" Khloe continued. "I have seen so many hurtful/despicable stories and tweets about me over a false story. And if it were true.... it's MY LIFE, NOT YOURS."

Back in April 2020, the 25-year-old supermodel sounded off on Twitter after reports surfaced that she and Devin Booker (who plays basketball for the Phoenix Suns) were an item. This response came about after several social media users suggested that NBA players were "passing" Kendall around.

"They act like I'm not in full control of where I throw this cooch," the Keeping Up With the Kardashians star shared.

When critics referred to Kylie's squad at "Plastic Rangers," the beauty mogul replied, "and we love recycling."

After Kourtney Kardashian showcased her family's Easter 2020 celebrations, critics tried (and failed) to bring the party down. "Bruh cut your son hair…smh," one follower wrote in the comments section. Kourtney replied, "Most gorgeous hair on Earth. Anyone who says otherwise ABCDEFG." But wait, there's more! When one user suggested that Kourtney had a "new dog every month," the Poosh founder quickly corrected them. "We've had Honey for years Honey Honey."

In Feb. 2019, Khloe stepped out for her first public appearance amid Tristan Thompson's cheating scandal involving Jordyn Woods. After attending her scheduled event, Khloe received critical comments on social media that did not sit well with Kim.

Along with a video of Khloe out at the event, one Twitter user wrote, "If someone cheats on you publicly. Y'all going outside the next day?"

After seeing the tweet, Kim replied, "Would you prefer she lose the [money emoji] too? A single mom has to work too boo! This was a professional commitment planned far in advance and you better believe she is not waiting on anyone to pay her bills or provide for her daughter. PERDIODT!!!"

While on vacation in Italy with her kids in 2018, Kourtney posted a photo of herself on a yacht with the caption, "just finished my daily basket of focaccia...hbu?" In response to the photo, one Instagram user commented, "Where are your kids?" After seeing the comment, Kourtney replied, "My son was taking the photo, and the other two were sitting a table across from me. Thank you so much for your concern."

Back in 2016, Kim took to social media to fire back at actress Chloë Grace Moretz for dissing her nude selfie. "let's all welcome @ChloeGMoretz to twitter, since no one knows who she is," Kim tweeted. "your nylon cover is cute boo." 

Kim also clapped back at Bette Midler and Piers Morgan for their critical comments about her photo.

After the infamous egg photo beat Kylie's Instagram record in Jan. 2019, the E! star took to social media to clap back at the account. In her post, Kylie shared a meme that read, "Kylie when she sees the world record egg account." Along with the meme was a video of Kylie cracking an egg. The beauty mogul captioned the post, "Take that little egg."

In a 2018 interview with E! News' Zanna Roberts Rassi, Khloe explained that she received criticism for going to a charity event without her daughter, True Thompson. "I was at a charity event last weekend and I'm literally trying to raise money for cancer research and I'm getting annihilated for being somewhere on a Sunday," Khloe said. "I'm like, 'She's with her dad, you a--hole. Like, what do you want me to do?'"

After seeing Alex Rodriguez's claim that she was "talking about Instagram and her lipstick, and how rich she is" at the 2019 Met Gala, Kylie set the record straight. "Umm no i didn't," she tweeted. "We only spoke about Game of Thrones."

In 2018, Kendall posted a photo of herself sitting at a rooftop table in lingerie. After seeing the photo, many social media users noted that the Kacey Musgraves billboard in the background appeared to be blurred.

Amid rumors of shade, Kendall clapped back, "yoooo, I was working all day and didn't edit this photo! Kacey is literally my f--kin fav! Space cowboy, I Miss You, Keep it to yourself, FOLLOW YOUR ARROW!! bangers!! ask anyone of my homies i die for her!"
