GACOU
A weird, annoying disease that makes your brain go all wobbly when you see someone cute. It's not deadly, but it can make you act like an idiot.
DM: 'Hey, why are you staring at me? Do you have GACOU?'
Text: 'I can't focus in class because I have GACOU for my teacher.'
Post: 'GACOU hit me at lunch. Now I'm crying in the hallway.'
