The art of throwing bananas at people in order to steal their food and/or money. Usually a last case scenario when trying sell bananas and/or exchange a banana for other food product. If you have had a banana thrown at you while your food was being taken, then you were banana slammed. A technique most often used when trying to trade a banana for a burrito.
Banana Slammer: "How much for a beef burrito?"
Vendor: "$4.00"
Banana Slammer: "All I have is this banana, wanna trade?"
Vendor: "No, sorry, cash only"
Banana Slammer: "Are you kidding me? This is a perfectly good banana!"
Vendor: "Four dollars please"
Banana Slammer: (Throws banana at vendor's head and jacks his box of burritos) "Take that, dildo mouth"
Vendor: "ouch, I was just banana slammed!"
