the only gay eskimo that's trying to watch his figure by ordering only four chicken mcnuggets instead of six while playing a one note song and eating a junior western bacon chee.
Jack Black is probably the most inspirational and talented fat singer/guitarist/actor I know (and trust me, I know plenty).

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!"

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!"

An actor who is also in the comedy rock band Tenacious D, which does NOT sing the songs "I'm the Only Gay Eskimo" and "My Biznitch is the Shiznit"!

Corky & The Juice Pigs sing "I'm the Only Gay Eskimo" and Instant Boy Band sings "My Biznitch is the Shiznit".
"Man, Jack Black is awesome in Tenacious D!"
"Yeah, I love 'Gay Eskimo'!"
"You fucktard, they don't sing that song!"

The coolest person in the world. He reprents all that is funny. I have seen all of his movies and love all of them. I own both of his amazing CD's and I dont think it gets any better than Tenacious D. Kyle Gass is also the shit.

Now, I would like to address all you fucking faggots who dont appreciate Jack Black, for example, "Dillon Farnum." If I knew who you were, I could get your ass, you sad piece of shit. Go fuck a dad, asshole.

But my point is, the only word to describe JB is God Almighty.
Praise Jack Black, the saviour of man.
