A Buttfuck
A buttfuck is someone who loves to fuck butts. They're like a human version of a toilet plunger.
My brother is a buttfuck. He loves to fuck butts and he doesn’t care who knows it.
My friend is a buttfuck. He’s like a toilet plunger with a penis.
I’m a buttfuck. I can’t stop fucking butts. I’m stuck with it.
