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

This person is either a great person or not. Jack is an annoying person often and is very sarcastic (sometimes good sometimes not).

Sometimes Jack can treat a girl well and make her feel special. The girl will fall for him however she doesn’t know he’s a fuckboy. Soon she gets pushed over the edge.

But there are good Jacks out there. Keep looking!

Girl: Jack’s such a dick. Why did he change?
Boy: Idk. He’s a Jack tbh.

Jacked

Shortened form of Jacked up.

The book you're issued for math is missing it's cover and the pages are torn. You'd say "That's jacked."
