A very moist boy-man-child with a creepy smile and a butters hairline. Jack will perv on girl's boobs and will, if encountered with the chosen female to bond with, he will perform a cleveland steamer to the woman's breasts. To meet a Jack is very unlucky and must be avoided at all costs, the Jack is most likely a French, thin young man that loves to moisten his very small ball sack. He loves to poke you on Facebook nonstop and in real life if you are not careful. Always carry pepper spray if you ever come across Jack. He is a very dangerous one that has Ebola and Aids.

Girl: Ugh there was this creepy guy at the club, I think his name was Jack

Jack is a very homely person, he always knows how to cheer one up, Everyone knows he deserves the world but unfortunately he doesn't, If only Jack knew his worth. Very kind and funny. Cute and charming too!

Oh boi it's a Jack, hide your wives

A man who can trick you into anything, even if your totally against it. Who only cares about his own well being, may seem like he cares about you but really doesn't at all. Usually mentally I'll in a crazy way, and very smart. Even if he is not that attractive he still has more charm than anyone, he says he loves you and makes you believe it till he doesn't call the next morning. When you ask about it he claims he is not good at the morning after thing. And you think it's cute. Over all just a tease, makes you fall in love then drops you on your ass.

josh: what's wrong with that girl? jack: she thought I loved her then i dumped her but continued to see her and tell her I wanted to get back together so I could get some josh: ooooh that's tough, she got jacked.
