Motherfucker is an English-language vulgarism. It is a form of the profanity fuck. While the word is usually considered highly offensive, it is rarely used in the literal sense of one who engages in sexual activity with another person's mother, or their own mother. Rather, it refers to a mean, despicable, or vicious person, or any particularly difficult or frustrating situation. Alternatively, it can be a term of admiration, as in the term badass motherfucker, meaning a fearless and confident person.
