Its an action of pulling a super slick CIAish move like Jack Bauer from 24. When you pull a Jack its something amazing that will save your or the whole world. When you Jack it means that you have just made a BEAST move or you have achieved superiority. When you pull a Jack it means that you have gotten yourself out of something that no one else could've except for Jack Bauer-Kiefer Sutherland

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."
