Boys don't realise how much calling a girl "fat"

Today, this guy called my best friend fat.

She started crying because he hurt her so much, she’s even on a diet because she thinks she’s fat. 

I started a chat with him and he told me “I only said it as a joke.” 

Guys who call girls fat as a joke are sick and mean.

My best friend is not fat at all by the way. All her so called “fat” is muscle. Literally. If she flexes, no part of her body will jiggle. 

Then people wonder why girls starve themselves to death, and why anorexia and bulimia are so common in teenagers.

Words hurt.
