Jack Black

One of the many names someone at school has made up in a desprate attempt to insult me. I actually find it quite funny. It's probably the most logical 'insult' I've heard since I do have a Jack Black-ish apperance, a feminine and younger Jack Black, of course, but still Jack Black-ish

The random asshole was childishly amused when he called me Jack Black.

Jack Blacking it

You know how Jack Black imitates instrumentals with his voice, like "brig digga dig" and all that stuff?
When someone does that, it is called 'Jack Blacking it'.
Popular among enthusiastic metalheads.

Steve: "DUN DUN DUN- wa nanana, nanana, nanana! DUN DUN DUN- wa nanana, nanana, nanana!"
Dave: "What is it with Steve and 'Raining Blood'?"
Bob: "I'm not sure but he's really Jack Blacking it!"

Jacking Black

The act of masturbating whilst really high so that when you jizz all the blood rushes from your head and you black out. May be hard to achieve.

Also called Knocking Off.

X: "Ben and I tried Jacking Black last night"

Y: "No Way! You guys are crazy! Any success?"

X: "Yep, I totally Jacked Black!! Ben didn't manage to though. It really isn't easy!"
