buttfucker 

This word can be used in two contexts.

The first and more common is an annoying, irritable, or unintelligent person.

The second is someone who actually engages in butt sex. This usage seems fairly uncommon these days, as the word has long lost its original meaning.

Matt, shut up you buttfucker.

Maybe I would hang out with you if you didn't act like such a buttfucker all the time.
