If u ever meet a Jack you are very lucky. He is funny handsome strong and cheerful. He would always make u happy and if u r ever sad he can make u happy. If a Jack find someone he really like someone he might keep it in or bring it out. He doesn't want to fight but if someone messes with his friend him or someone he really like he will make u look like a JACK ASSSSS. In sum if u ever meet a Jack you r one of the luckiest people ever.
Jack is the best in the whole world.
Really just a sarcastic asshole, can be nice at times but makes you step back and wonder whether or not he's being serious... probably not.
Person: Hey did you hear the joke Jack made the other day?
Person 2: Are you sure he wasn't just being a dick?
A guy who probably still plays with hot wheels in his basement even though he's a teenager. He also runs like an elf that's under the influence.
Jack, you gotta stop with those hot wheels, or your mom is gonna stop feeding you bagel bites.
if your name is jack then your probably the popular guy in school that every one loves but if your a brother or sister to this person than you guys fight a lot and jack is also very annoying.
jack: your probably are the popular guy and you don't do your homework.
