Banana Yellow 

when riding in a motorized vehicle, hopefully with people you know, you are at a stop light, stop sign, on the highway, or just driving to your local convienent store to grab a slushy and some hot cheetos.. while in the car you see a different vehicle either on the road or parked in a near by lot for parking and the color of this vehicle is yellow, like a banana. hence the term, banana yellow. the first human to see this yellow vehicle yells out, " banana yellow" and hits every body else in the vehicle they are traveling in. if this person does not want to be hit back he or she says "banana yellow, no banana back" hence, resulting in a successful banana yellow attack. ah yes.

* in car *

-Person1: " banana yellow, no banana back"( hits passenger(s) next to him)

and laughs histerically saying" yess nigga yess i got you"
