Used as a greeting to a long lost friend after a long time - "mother - fucker" has nothing to do with sex with a mother.
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!"

Get the MOTHER FUCKER mug.
This has 2 meanings:

1. Literally it means someone who has sex with his own mother, but this word is hardly used in this context(Just like when you call someone a bastard, you don't mean he is a bastard child, when you call someone a mother fucker, you are usually you are not implying that he is someone who sleeps with his mother).

2. The mother of all fuckers(this is what people actually mean when they call someone a mother fucker).
definition 1:

Tom: Go fuck your mother...

Jerry: Only a mother fucker(the context of this word is literally someone who has sex with his own mother) like you will do such things.

definition 2:

50 cents: Yo mother fucker! wassup!

Eminem: yo fiddy...nothing much...hows it going?
