Definitions Revealed

I'm sure many of you have been waiting with bated breath for the definitions to "dub sac" and "twamp." So, without further ado:

Twamp: It's slang for a twenty-dollar bill, as in: "I earned a twamp mowing lawns."

Dub sac: It's slang for a dime bad, as in: "Tomorrow, come by the apartment, and I'll hook you up with a dime bag."

Now, I've been asking everyone I meet if they've ever heard of "twamp," and so far, no, no one has ever used the term. Ben, though, insists they are So Cal term, so maybe when I run down to LA I'll test out the terms on the populace. I'm expecting a lot of puzzled looks.
