An italian male who tries to be guido but fails. Unlike other italians, a nizzie is not tan, nor extremely good looking, or guido. He achives bulky muscles by juicing, although he will deny it. A nizzie swears that he is hot, everyone wants him, he's tan, and buff, although none of those are actually true.
EW! Look at Nizzie! He's soo pale!

There goes that Nizzie again, buying steroids.

That Nizzie is a poor excuse for an italian.
