A Mandinga is simply a man from Dinga. Dinga is a town where such poeple like Chuck Noris originate from. So a man of Dinga can be considered a badass or a cool guy. So there for Mandinga is a slang word for a badass cool guy, maybe a friend, uncle, neihgbor, I dont know anyone who fits the discription. In other words, it is not a sex act or a devil, simply a comment or title given to someone.
