An insult or an explitive, addressing somebody who sleeps (ie. has sex with) one's mother. Often used to describe someone that you hate, but it's also used among close friends as a term of affection. Still, in a way, a father, stepfather, or stepmother is a motherfucker; who else would be fucking one's mother?
