To steal or thieve, usually in a way that is in the spur of the moment and without any deep planning.

Just plain amazing! He will always be there for you and give the best hugs in the entire universe. He's so cute and funny and will always be by your side through thick and thin. He loves music and his guy friends and is very loyal to his girlfriend! He's so good looking and when you get to know him, he's just so amazing.

Even tho they are like 14 you act like an 18 year old, every guy who's named jack is a horny fucker and is bad kisser. Ever girl falls for him but they don't know there down side. They are gay and can't control there feelings and never get over there ex's, they either date you because they just don't want to be single or they use you for nudes or making out. They think they are so hot and sexy and that there absent hoodies are so cool but really it's the opposite, the fact they show off every single minute is so dumb. They always listen to depressing music like juice world and they get shit loads of girls. Really just don't date anyboy who's called jack.
The gayest person who could ever existed is a boy who's name starts with J and in this case we are talking about Jack. Don't date them

If you know a Jack you are the luckiest person alive. Fist of all Jack's are really hot and cute. Plus boyfriend material. If you ever run into a Jack he is a keeper never let him go. He is also a great friend he loves to joke around and he is sporty. Jack's are always going to be their for their friends no matter what happens. They are really hard to break a friendship with, but if you do you will regret alot.
Girl: Omg is that Jack
Girl #2: It is he is SO hot
Girl: No Duh he is a Jack
