pain-popping
A pain-popping is when someone says something so rude that it makes your face turn red and your brain scream for mercy.
My crush told me he only dates girls with perfect grades. I got a C on my math test. That was a pain-popping.
My dad said I was too messy to be allowed to stay out late. I felt like the worst kid ever. That was a pain-popping.
My teacher called my drawing 'the worst thing I've seen since the last movie.' That was a pain-popping.
