A hot guy, which stands way above the rest. Very athletic, intelligent, articulate and charming; the complete package. Most males strive to be "Nizz", but unfortunately for them they can only imitate and never duplicate. If you are a true "Nizz", you can get away with lines such as, "I'm the Nizz and nobody beats me"...cause it's true!! Nizz is something that you are born into; top of the hierarchy in a caste system.
