multimaniac
A multimaniac is someone who is so incredibly good at so many things, that people start to think that they are clinically insane due to how much experience they have in so many fields. Very similar to a workaholic, but much worse due to the fact that they pursue hobbies along with work topics. Also could be considered a major dick, depending on how they come across in conversation.
“Hey man, did you hear about the new guy at work? I heard he’s licensed in carpentry, welding, machining, designing and plumbing, and on top of that he’s a professional photographer, extremely good at knitting, and a professional big game hunter?”
“No dude. He’s insane. Beginning to think he’s a multimaniac because all he cares about is his credentials”
