pain-popping
A pain-popping is when someone says something so mean that it feels like your brain got kicked by a donkey.
My teacher said I was the worst student ever. I wanted to scream. That was a pain-popping.
My brother told me my haircut looked like a raccoon. I ran out of the house. That was a pain-popping.
My crush said he only likes girls with straight hair. My hair is curly. That was a pain-popping.
