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

Jacks usually have feelings for a person but they are too shy to tell them. The people they like probably like somebody else but they don't care. He is smart, funny, awesome, handsome, and doesn't care about what other people say about him. If you know a Jack you are one lucky person to be his friend! :)

Jacks are the sweetest, kindest most amazing guys you’ll ever meet. They’re hilarious and will always turn your darkest days into the brightest ones. If you manage to be great friends with a Jack then boy you’re lucky. Jacks will always be there for you and listen to what you have to say. They’re super athletic and cute but super humble at the same time. Jacks will always help you out, they’re very intelligent and logical. They’re just amazing. Jacks are one of a kind and will make you feel so special. If you ever find one, don’t ever let them go. If you do then that would be a terrible terrible mistake
Damn, that’s a Jack alright!
