To pull a Jack is to shit on the top of a car then sit in it. Then hold your legs straight up as high up as they can go. Then to grab your toes. Then slide down the windshield screaming "AARRMAAGGEEDDOONN!!!!".

My mom was so pissed when I pulled a Jack on her new car...

Jack is the sexiest guy you'll ever know. :) When he smiles, I smile. His gorgeous eyes give me chill bumps. His athletic abilities make me stare in awe. The way he adores me lets me know I'm not going to lose him anytime soon! ♥
I love Jack!!!

Jack exemplifies perfection.

He's around 6' tall with dark hair, an amazing rock hard body, and devastatingly handsome features. He has cool calm and confidence that both intimidates and exhilarates all women.

He is a leader who rules with a benevolent yet firm fist. He commands authority, but those that follow him, follow willingly because they recognize that he is no ordinary man... he's practically a god that will surely lead them to success and happiness.

He has a subtle and sarcastic sense of humor that not everyone will get (dumb people). But if you share his humor, you'll find that Jack will have you constantly giggling.

He's an amazing lover. His affection can be difficult to win over, but once you do, he will be devoted to you completely, and make you feel a happiness unmatched by anything else. As a bonus you'll find that Jack is incredible in the bed. While kind and gental in person, you'll find that he's quite the opposite in the bed room. Be prepared, Jack likes to get a bit rough with girls, displaying his dominance in the bedroom... it also helps that Jack is well endowed.

Jack only has one flaw: Once you meet him, the world will feel a bit dimmer when he's not around. Fear not though, this sadness will only last until the next time you see him.
Girl 1: "omg Jack made me cum so hard last night... I didn't know that kind of pleasure was possible..."

Girl 2: "so jealous.. I need to find me a Jack."

Suffix meaning "to steal", generally applied to a vehicle or situation. Originates from the word hijack but bastardised for comic effect.
Dude 1: I was gonna go for a crap but someone's running a bath.

Dude 2: You should have jacked it.

Dude 1: Bathjacking?

2) Term referring to Dubliners, since they uphold British traditions more than any others in Ireland. The name comes from when they waved Union Jack flags during a visit from the Queen.
