Used as an exclamation: "hey!! I just won 14 million on the lottery!...". Reply: motherrr-fuckerr! or, you murrrer! (for short)
Also, say it with expression mother fucker! Or as a prelude to entering conflict with an enemy: "Come here mother fucker!!" That sort of thing. "He skidded on some diesel and hit the tree but he's alright": reply exclamation: "mother-fucker!"
