A pretty cool guy, who's well-known as player. His full name is actually Jack Sparrow. If you ever see him, you should try to get his autograph immediately.

The ultimate head fuck.
A Jack will charm you, whoever you are. He will be the swetest person ever to you, make you feel like the only girl in the world and he's gorgeous.

But beware, he's a player, a liar, and a fighter with a hot temper.

He will make you fall, then let you down, beg for forgivness and you will forgive him and he'll do it all again, always.
Girl1: I love him, but I hate him. He's so confusing!!
Girl2: Looks like you've found yourself a Jack

1) Irish slang for toilet. Derived from Union Jack, the British flag.

2) Term referring to Dubliners, since they uphold British traditions more than any others in Ireland. The name comes from when they waved Union Jack flags during a visit from the Queen.
1) Lads, I'm bursting for the jacks.

2) Ah, fuck. A bunch of jacks.
