Its when you warm a banana in a microwave for 30 seconds or until slightly warm and stick it in a your ladies bum with 2 scoops of your favorite ice cream, hopefully not chocolate, add toppings and use her butt as a bowl...
I jus gave my girl a dirty banana split and it was finger licking good.

Get the dirty banana split mug.
Where the guy deep throats your dildo while you put cherries up his ass and fuck him with a frozen banana. Later he will take a shit seeing the cherries and banana.
He saw the after math in the toilet from the dirty banana split.
