Jack

The person who aspires to be all the other definitions you see here, but is really just an egotistical asshole who thinks he's smart and funny.

Guy: Did you hear Jack got fired?
Guy 2: That asshole had it coming.

Jack

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
