A Buttfuck
A buttfuck is when someone shoves their penis or a dildo so far up your ass it’s like they’re trying to colonize your rectum.
My brother gave me a buttfuck. He used a dildo and I still can’t sit down.
My ex gave me a buttfuck so hard I felt it in my brain. He’s a buttfuck.
That guy at the party gave me a buttfuck with a cheeseburger. He’s a buttfuck.
