Kangaroo Jack 

An unbelievably bad movie, that involves a smart ass CG kangaroo, and an unlikely multi-ethnic duo of ass tards trying to get a jacket back from said Kangaroo. (Jack)

I hated Kangaroo Jack so much, I shat myself in the theater just to have an excuse to leave.

nut jack 

When you are hitting on a guy and another girl/guy swoops in and steals them away.

I was talking to Matt and Christa came over and nut jacked me.

Whenever I got to the club with John, he always nut jacks me.

Sloppy Jack 

When a semi-flaccid penis is flung violently in a whip-like motion towards a women's face or genitals, usually causing semen to become airborne.

"How did your date with Brenda go last night?"

"It was nice, we went to dinner and afterwards I gave her a big fat Sloppy Jack. There was semen everywhere."

Black Jack Johnson 

Mos Def's rap-rock band. You can hear Black Jack Johnson on the song Ghetto Rock which is on Mos's album The New Danger.

Person 1: Yo, did you hear Mos Def started a band?
P 2: Yeah, Black Jack Johnson, I heard he did it because he says that Rock bands have no soul like Limp Bizkit.
