Motherfucker (sometimes abbreviated as mofo, mf, or mf'er) is an American vulgarism. Its literal sense, referring to one who participates in sexual intercourse with a mother, either someone else's, or his own is seldom implied. Rather, it refers to a mean, despicable, or vicious person, or any particularly difficult or frustrating situation or alternatively as an inverted praise of the individual or thing's "badness". Due to the semiotics, it is not generally applied personally to females, a personal direct object referred to as such is invariably male.

Like many widely used offensive terms, motherfucker has a large list of minced oaths. Motherhumper, motherfugger, mother f'er, mothersucker, motherlover, mofo, motherflower, motherkisser and many more are sometimes used in polite company or to avoid censorship. The participle motherfucking is often used as an emphatic, in the same way as the less strong fucking. The verb to motherfuck also exists, although it is less common. Conversely, when paired with an adjective, it can become a term denoting such things as originality and masculinity, as in the related phrase "bad ass mother fucker".

Kid Rock released the follow-up in 2001, Cocky. After a slow start, his country-flavored hit "Picture" with Sheryl Crow resurrected the album and it went gold as a single and pushed the album's sales over 5 million. It was followed by 2003's self-titled release, which went platinum in the USA and reached No. 8 on the Billboard charts. In 2006 he released Live Trucker, a greatest hits live album that went mostly unnoticed.
