Motherfucker

Motherfucker is a vulgarism. Its literal sense means one who has sex with his mother, although this usage is seldom implied. Rather, it refers to a mean, despicable, or vicious person, or any particularly difficult, tough or frustrating situation. Alternatively, it can be used as a compliment. Due to the semiotics, it is less often applied personally to females; a personal direct object referred to as such is usually male.
