Motherfucker (; ), sometimes abbreviated as mofo, mf, or '''''mf'er, or just simply mfer,' is an English-language vulgarism. It is a form of the profanity fuck. In common usage, it is rarely used to refer to one person having intercourse with a woman who is a mother. Rather, the word usually refers to a mean, despicable, or vicious person; or any particularly difficult or frustrating situation. Conversely, it can be used positively, as a term of admiration, as in the term badass motherfucker (), meaning a fearless and confident person.
