Jack is a small creature, of Irish origin, known for it's easily disrupted temper and compulsive lying. Jack's love to make threats that they well never deliver, not only this, but they get all up in people's faces when they are challenged, clicking their fingers as they do so, to try and seem larger then they really are. Most Jack's are pessimists, always attention seeking when a problem occurs.

jack is usually a sound kind of guy, jacks love oral sex and secretly are gay.
Most jacks are short for the term JACKass.

Blonde Jacks think they are all that and a bag of chips, but they are not. They think they know everything when all they really know is how to eat shit.

Jacks loves everybodys mommas so keep them locked up away especially your fathers, cause god knows jack would give them the death.

Jacks may be muscley and think they are great but beware as jacks are hot tempered and like to box anything in sight... even a blue bottle fly

Jack comes from the meaning of a simp

Jacks also likes big booooty boys for a good time, and usually love spending their time playing gay rugby and touching up other lads.
oh your sucha JACK!

he gave it to him up the jack last night
