Motherfucker

Motherfucker (US: ; UK: ), sometimes abbreviated as mofo, mf, or mf'er, or just simply mfer, is an English-language vulgarism. It is a form of the profanityfuck. In common usage, it is rarely used to refer to one person having intercourse with 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 motherfucker (BAMF), meaning a fearless and confident person.
