Banana Fight is a skit in Asdfmovie4 where a man who was holding the banana yells out "Banana fight". Then the off screen person kills him and denies it.
Man 1: Banana fight!
(man 1 gets shot by off screen man)
Off screen man: NO!
Man 1: Hey, want a banana--
(Man 1's banana gets shot out by off screen man)
Off screen man: HEAD SHOT!!!
(Man 1 screams)
