A fork of Rural Dictionary
In Polish language: A male who allows other men to fuck him in the ass. Probably taken from prison slang. Currently used outside of its literal meaning, similar to English "motherfucker", but still a heavy insult.
There is also a derived verb: "cwelić" - to force-fuck someone in the ass
