These Kids Today...

I admit, I've been out of touch with the kids for a long time... I like to think that I know all the slang words, I just can't use them convincingly. But there's one slang word that I really can't get the hang of.

"Crunk"

As in: "I'm 'bout to get all crunk 'bout him."
Or the banner at the football game: "Tigers Get Crunk!"
Or at the state championship "They all crunk 'bout winning."

Is this word used anywhere else in the world, or is it just an urban southern type thing?
