Madafaqa
A word so strong it could knock out a bull, and it means you're the worst kind of motherfucker.
My dog barked at me and I said, 'You're a madafaqa!' and he stopped barking.
I failed my math test and my mom said, 'You're a madafaqa!' and I cried.
My brother took my video game and I said, 'You're a madafaqa!' and he gave it back.
