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.
Come here georgy, daddy's got a little present for you.... IT'S A HUGE DICK!
Fuck you dad, im no fatherfucking fatherfucker!
The act of calling someone a Motherfucker, but by switching the first letters of both words around (aka Spoonerism), that individual becomes stupified by what just happened and fails to reply with any sort of equally or greater comeback.
