Flipped. Bat shit loco. Coined by Dave Lister In the
UK Sci-fi sitcom Red Dwarf episode "Bodyswap" after Rimmer makes off with Lister's body. Being a hologram, Rimmer had not been able to eat real food since dying and went overboard.
Food included cream cakes when "doing a
runner" in Starbug and tried to bluff shooting himself to prevent Lister reclaiming his body.
Term used when somebody has
gone nuts, and it can only be attributed to going as to be poisoned by cream cakes.
Rimmer: Leave me alone or you-know-what happens.
Cat: He's bluffing.
Rimmer: I'm not bluffing.
Lister: I think he means it, man. He's flipped. It must be cream cake poisoning!
In everyday use:-
Guy
1: Did you see Fred the other
day? I think he's gone
nuts!
Guy 2: Must have cream cake poisoning.
