Jack

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.

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.

Jack

A slang term used to describe someone who is either lousy, frustrating, inadequate, arrogant, or just downright wack.

Someone can also “jack you” as in screw you over.

Amir was being such a jack last night, he refused to help me with my homework.

This store is ran by a bunch of jacks, go elsewhere.

Jack

Comes from the infamous "Car lot lingo". A "Jack" is a customer that strolls into a car lot usually holding a note pad or a portfolio of some sort with quotes from other dealerships, specs of vehicles etc. Sometimes Jacks may even show up with a measuring tape of some sort. The reason they are referred to Jacks is because they "Jack off" the car salesman to get information out of the salesman with out any intention of buying a car from them. In other words a Jack will shop you and research you and buy from somewhere else thus the term "Jack" for "Jacking you off" Only seasoned and experienced Car Salesman can spot a Jack at first glance, its usually the Green Peas or the inexperienced salesman that gets Jacked royaly with out even knowing it

John: "Ive got these two walkers in the front line!"

Peter: "Wow!, good call John!! hope you can sell them a car!!"

Paul: " HAHA, hey Chris look, those are big fat Jacks coming this way, poor John he's about to get power stroked!! Let the Jack session begin!!"
