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...

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.
