Bananafishbones, or bananafishbonesing is a state in which you are unlike yourself and engaging in serious crackhead behaviour. Derived from the song by The Cure of the same name which is not only fairly chaotic but embodies the mood and general energy of it to a T, to go Bananafishbones is to simply lose all inhibition and tweak the fuck out.
Person 1: Did you see Ana the other day?

Person 2: Yeah! She was Bananafishbonesing!
Person 1: she really did go Bananafishbones on us.
