JackMonkey 

1. An unfathomable moron
The word JackMonkey was origonally a derivative of "jack off" that was created in a moment of absolute frustration. The defining factor of a JackMonkey is their inability to grasp even the simplest concepts that are new to them.

I tried to teach that JackMonkey to tie his shoes but all he managed to do was get his fingers stuck in knots.

Regular jackoff 

Also spelled "Regular jack-off", the term is used in the Adult Swim show Metalocalypse to describe anyone that is not in Dethklok. Mostly applied to fans of the band.

Toki: What's this place called?

Skwisgaar: This is, I believes, called food libraries.

(The two practice saying "Food libraries")

Pickles: It's called a grocery store, ya douchebags! I'm sorry about douchebags. I got... got low blood sugar.

Nathan: Alright, here's the deal: we have to do our own shopping so we can make our own dinner like regular jackoffs do. Now you're all in charge of putting together one dish. And don't just buy booze! That ain't food!

Murderface: What do you mean, "booze ain't food?" I'd rather chop off my ding-dong than admit that!

Toki: You'd rather chop off your ding-dong than not drink?

Murderface: Yeah!

Toki: Wowee!
