A Trogger
When someone gets mad over something stupid or thinks they're right when they're not, they're troggered.
My mom got troggered because I wore socks with sandals. She flipped out like I stole her last slice of pizza.
My brother got troggered because I beat him at video games. He screamed like I broke his favorite toy.
My friend got troggered because her crush talked to me first. She cried like I killed her dog.
