Captain Jack Syndrome

When your inner compass points you towards booty, the thing you most desire.

Nick: Damn, what was up with Rob last night? Never seen him hunt a girl so hard.
Mike: Ah dude, she is the hottest girl in school! That booty gave him Captain Jack Syndrome.

May also be used as a derogatory term for somone who’s a POS.

My neighbor is a real jack knuckles. He’s always giving himself a wank online.

My uncle is a jack knuckles. I catch him tossing off every time I walk past the den.

Fuck that guy. He’s a jack knuckles.

Marvel Jack

That knobhead who goes to the park with you and your mates, yells wogwan at every person there, then gives himself brain trauma with an inanimate object.

Person1: Did u hear about that fucking kid
Person2: The one who tried to look cool by running up a skateboard ramp then fucking smacking his head into it
Person1: Yeah lol, what a Marvel Jack. He can’t read or write anymore
