A stupid person. Because the word isn't in great usage right now, referring to a person as a "nitwit" can be considered a more intense way of insulting them.

Cole: "Who do you think you're talking to?"

A cocky bastard that uses those shitty cheap ass "Nut Passes" during No Nut November. The guy might even download the image so he can reuse it and continue to jerk his dick like a tire pump and say he won something. This guy probably cries when he doesnt get a participation trophy.
Bruce: Carter has already jerked off 13 times, and its only November 4th!
Adam: What a fat shit, I heard he uses nut passes as an excuse to reproduce with his hand!
Bruce: What a No Nut Nitwit, I bet his hand smells like crusty socks and expired milk!
