Jack

Jacks are the biggest cunts ever, no jack is cool and they have no friends and are probably adopted. Great at footy but a major cunt.

"Wow is that jack playing soccer?"

"Yea, he's really good! but what a cunt"

Jack

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."

Jack

He's one hell of a person. He is very outgoing and virtuous but he is also a player. If you know a jack you are lucky but be careful because he might reel you in to get what he wants. Be cautious because he is very smart and witty. He's an amazing friend but has a problem with only looking at one girl. If you are dating a jack I advise you to be cautious.

Who's he?
His name is jack,He's a player be careful

Jack

Somebody who can't get their own fucking ride. Seems to always be jacking off when he's needed. Thinks he's Mr. Steal your girl but just takes away your happiness and will to live. Has a twiggy body build and looks like a piece of paper if seen from the side. They will act buzzed after one juul thinking it actually caused their balls to drop. They make one good fucking wingman causing your looks to skyrocket from their noticabley big nose and Jewish physique.

Short for JACKASS

Bro this kid can never get places on his own, he must be a Jack.

Yo this kid thinks he can actually get my girl. This dick must not know his own fucking name.

This kid is "buzzed" After one whiff from a juul. What a fucking JACK
