LITERAL TRANSLATION: O.K. ñema means cock or dick. So is basically like the word "mamaguebo" which means "
dick sucker". "MAMA" in this case comes from the verb " Mamar" which means "suck".
WHAT IT ACTUALLY MEANS: it is slang for "ma nigga" "yo, bro" (if you're really close) "you
fucking asshole" if
you're mad at the person.
