Get the Jack of all trades mug.
A term used to describe someone who knows a lot about many things, but, with the second tag "master of none" added it transforms into a derogatory phrase meant to emphasize how mastery of one skill is important for deeper knowledge.

However, one, oft forgotten tag is the third one: "is oftentimes better than a master of one". Instantly, the term reverses meaning, symbolizing how a person who knows a lot about many things that integrates their skills allows them to surpass even a master of one.

Interesting phrase, nonetheless.
"Man, Tom knows a lot! He's a jack of all trades, aint he?"

"Yeah, but he probably doesn't know a lot about specifics. You know how it goes: Jack of all trades, master of none."

"Jack of all trades, master of one, is oftentimes better than master of one, man. Tom's pretty smart."

Get the jack of all trades mug.
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?"
