A male or female who has had so much anal sex in their lifetime that their asshole gapes open much larger than the average anus. You can detect a fuckbucket in many ways. For example, if a person farts and it sounds like someone blew through a glass bottle, that person is more than likely a fuckbucket.
Dude, did you hear that girl fart? It sounded like someone blew air through a beer bottle! Five bucks says she's a fuckbucket!
