Jack is someone who is exceptionally gay and has a secret(or many secret) relationships with boys. However he tries to hide this by chasing skirt and basically getting as much pussy as he can. Sometimes he may truly have feelings for the girl but he tends to prefer men. The signs of being gay are all there and many people say that he's gay but no one really thinks it.
Girl: You know Danny right?
Boy: Yes! Oh my god he is so fit!
Girl: What the fuck?! Your such a Jack.
Boy: No I'm not. Suck my Dick bitch.

Jack is a flamboient fello who enjoys reciveing more than giving. He is use to a bit of anal and enjoys the company of the younger generation. He is un-loved by alot of people and he makes it too obvious that he likes penis'. He likes to shove his tiny penis into the exhausts of shitty cars. He thinks that his SAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAB is the best thing in the world and he like to overuse shitty jokes to make people like him even though he's a cunt. He is a massive smelly Coon and he takes his time when walking past a playground full of small childeren. You can tell by the tiny boulge in his trousers that he is aroused by this.
QUICK RUN! I think there's a Jack about.

Holy shit Jack found us.

A giant tool and not a cool guy.
Guy One: "Man did you see that Jack earlier?"
Guy Two: "Oh yeah, he's a POWERtool."

An amazing, extremely attractive guy with a wonderful personality. He keeps to himself, but even so is constantly hit on by girls lusting for his good looks. Even though he's kind of a loner, he will always be there for his friends and those he loves. He loves the color black and Japanese rock music, as well as anime and video games. He's a wonderful nerd who any girl would be super lucky to have.
"Wow, you see that guy over there? He's a real looker."
"Excuse me?"
"That guy standing there all alone in black. I usually don't go for that type, but god, that Jack is hot!"
"That's my fiancé you're talking about."
". . . You're the luckiest girl in the world."
