Crazy mofo who will rek ur life...in a good way. Everyone talks about him but he doesn't realize it, is the hottest guy at ur school. Probably played minecraft as a kid. Is definitely the craziest person in ur squad and will beat anyone at physical combat.

Can do as many backflips in a row as you tell him to do before losing consciousness. Will attempt any challenge without question.

Will be the first to submit to any form of authority, and will most likely become a killing slave...prepare for the apocalypse.
A: "Hey, would you mind taking my pic? I gotta go backflip off that cliff."

B: "Yeah, sure dude. Ur such a Jack."

A Jack is a small neckbeard incel that expects the world to be on his side and everyone to be friends with him. It can also be used for a guy who faps to curry.
Calling someone a Jack is a very bad insult and should never be said unless you want to mentally destroy your opponent. If someone is called Jack then that doesn't mean that they are a Jack.

Person A: Hey your a Jack!
Person B: Hey shut up you asshole speak for yourself you curry fetishist.
Person A: Okay you got me. We are even.

Jack is a kind boy and is also very smart. He likes to play various sports even though he's a little on the short side. A lot, and I mean a lot of girls like him since he is the way he is. He's sweet, just don't get too attached.
Jeez, way too many girl like Jack.
