Jack of All Asses

A person who has the ability to piss off anyone at any time, and anywhere. Typically, these people are unpleasant to be around due to the sheer amount of ignorance they emit, or lack of caring while being an asshole. They never fail to make someone's day more unpleasant than what it would, or not, have been. Atop of this, they also seem to be capable of this in more than one way and rather effortlessly, hence the name "Jack of All Asses.".

Person 1: "Man, I can't believe how triggered people were at the funeral. All I said was "I'm pretty sure this guy owes me 5 bucks."

Person 2: "Wow, you really are a Jack of All Asses aren't you?"
