pain-popping
A pain-popping is like getting hit with a bag of bricks and then being laughed at by the whole class.
My dad said I was too lazy to clean my room. The entire family laughed at me. That was a pain-popping.
My friend said my drawing looked like a blob. I was crying in the corner. That was a pain-popping.
My crush asked me out and then told everyone I was 'just average.' That was a pain-popping.
