What does motherfucker mean exactly?

[Anonymous]

In Turkey, Turkish translators always translate this word from Hollywood movies as "son of a bitch" or "damn, goddamn, curse you" etc.

What is the true meaning of this word exactly? It is like there is a guy who is a fucker machine and he fucks his own mother all the time.

It means you fuck your mother. It's a fairly strong insult

Depends on context
