“Psyche!” was a popular one for a bit in the late seventies. Short for “psyche out” as in “to psyche someone out.” To fool someone into believing they would receive a favor or treat and then immediately withdrawing it. (A little different from what the list says.”
“Did you say you wanted the last beer? Here you go... Psyche!”
Eddie Murphy used “Psyche!” in his stand-up “I’ve got my ice cream” routine.
“I got my ice cream! I got my ice-cream! And you ain’t got none! I got my iiice creeeam! ...Wanna lick? Psyche!”
I never heard it.
