When the people at gamestop buy your 50$ game for 9$, then they put it right back on the shelf for 49.99$.
Clerk: Hi welcome to gamestop, can I interest you in a buttfucking.
Customer: No thanks, I'll just sell my shit on ebay.

When two or more people are using "teamwork" to be cunts in agario ffa.
I was coming second in agario but then 2 buttfucking cunts killed me.
Got to the top of the leader board on agario even though there were 2 buttfuckers in the lobby.

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.
