Similar to a
motherfucker. But a specific type of
motherfucker who is a despicable and dirty-minded.
It can mean precisely as it sounds, one who has sex with cum, but it was originally meant as "one who has sex with with there own or others cum”
It is most of the time used without meaning, just to be said in a sentence, it can mean
absolutely nothing and absolutely everything its meant to at the same time. Just describes a really shitty person.
