I saw this defined multiple times, and all of the 5 definitions I poured over had gotten a large negative vote spree. So I thought that this would help anyone who has to be looking for the definition of a "Nut job"

The "Nut Job" has nothing to do with Sexuality. It is completely and utterly the term used to describe a Maniac, Just like a Nut Case.

In other words, it is an old man or stalker that has lost his mind; Or just a Hyperactive person that is all over the place and always looking for fun

(I don't always use the term do this example is going to be crappy)
Person: "Did you see that old man walking down the street?"

DesertedChrome: "Yeah, I heard about him. He got arrested for multiple charges. He's a Nut Job"
