Another word opposite of motherfucker, as like fatherfucker, a female who gives fellatio to her father. Used as insult, can be used by both sexes to a female. Also can mean a prostitute who has a pimp who she "sucks up to him". Also can mean "daddy's (favourite) little daughter/girl".
That fuckin bitch is a fathersucker.
