The title of Canadian pervert Peaches 2003 album, the word fatherfucker has also become a fun new insult for the female persuasion.

one who fucks fathers

The opposite of the word Motherfucker.

A motherfucking awesome album by Peaches.

A term redefined as a catchphrase for Glaswegian comedian Frankie Boyle, on his sketch based comedy show "Frankie Boyle's Tramadol nights", termed by one of his sketch show characters, an abusive cowboy, who first termed it when asking th ausidnece to choose an actor from "Brokeback Mountain" they'd rathe fuck, Heath Ledger or Jake Gyllenhaal, and after getting a strong feeling of Heath Ledger, says he would have chosen "The guy's wife you FAGS!" saying that he gave those two names as suggestions, then invites the "Fags" to come fight him saying "Bring your life partner, cuz I'm gonna show you heavy, Fatherfucker!" the phrase has now stuck with the character for, presumabely, the series.

n. A variation on the popular "motherfucker", a fatherfucker is one who fucks one's own father, essentially the female context of motherfucker, a fatherfucker may be male however, not only implying incestuous deeds, but homosexuality as well. Loses its value on the wife of a father.
