A perfectly yellow, ready to eat banana that a woman puts in her purse to eat when she is on the go. However, while in transit, the banana becomes overly bruised, bounced around in the bottomless abyss that is her purse.

Ultimately, by the time the woman gets to her destination, the banana is brown and mushy.
By the time I got to work, my yellow banana turned into a purse banana. I had a few unsatisfactory, mushy bites then I tossed it.

A vegetarian alternative to the meat wallet. A sweet set of lips that leads to a holding area, or purse, for the above mentioned banana. Usually found on granola hippie chicks that would never allow meat to penetrate their openings.
