Bust a Benjamin 

The act of taking out and using a $100 bill to pay for something. (Due to Benjamin Franklin's portrait on the bill).

"That'll be $96."
"Ooh, looks like I'll have to bust a Benjamin on this one..."

After you hand someone else a $100 bill, your friend might say:
"Damn son, who busted a Benjamin?!"

Fork over the $$, especially when it's earned, don't be so tight-assed, stingy - SHARE!! You're in business for yourself, and someone just keeps you hanging and won't spend any, but feels perfectly justified wasting your time.

Dude, bust a benjamin (stop wasting my time), will ya???
