Definition

A hundred-dollar bill, because apparently "Benjamin Franklin" was too many syllables for people counting their cash. Named after the founding father gracing the C-note, this term is popular among those who like to sound casual about large denominations.

Example Usage

I've got three bennies burning a hole in my pocket—should probably pay rent instead of hitting the casino.
