Motherfucker (sometimes abbreviated as
mofo,
mf, or
mf'er) is an English language
vulgarism. Its literal sense means one who
fucks and/or engages in
sexual activity with another person's mother, or his or her
own mother, although this usage is seldom implied. Rather, it refers to a mean, despicable, or vicious person, or any particularly difficult or frustrating situation. Alternatively, it is used as a compliment, for instance in the
jazz community.
