It used to be acceptable to make fun of people because of their weight. But thanks to the body positivity movement, a growing number of people are proudly standing up and proclaiming that beauty comes in all shapes and sizes.

One guy who clearly missed the memo and paid for it dearly is Leyton Mokgerepi from South Africa.

Mokgerepi not only tried to fat shame a woman on Twitter, he chose to do it to Lesego Legobane, a plus-size model, blogger, and body positivity activist.

Big mistake.

Mokgerepi created a meme that compared Legobane with a thinner model, Joëlle Kayembe, that reads, “Girls that I like vs. girls that like me.” The sizeist joke claims that he likes thin women, but only larger women like him in return.

Legobane tweet-slapped Mokgerepi back to the womb with one perfect sentence.

The tweet got over 300,000 retweets and was liked by over 940,000 people, including Nicki Minaj, Ariana Grande, and Ava DuVernay.

Mokgerepi thought he could set things right by saying Legobane was his ideal woman, but nobody bought his BS.
