If your banana tastes really good then you describe it as a "banana banana"
It is the way a banana should taste.
example: a banana flavored candy tastes like a banana banana but a regular banana is just a "banana", sooo if you have a banana that tastes really really good it is a "banana banana". noww if you have an even better one then Its "banana banana nana ana"
banana no banana back is where if you see a yellow vehicle you hit the person in the car and scream banana no banana back so they canβt banana you back
