Psyche Regret

When someone, usually an idiot, chooses to say psyche after something that would probably in retrospect earn them props.

This is usually followed by the idiot saying awww or damn it.

Guy: Guess who got laid last night? I did!!
Friends: Really?
Guy: Psyche!! Haha
(silence)

Did i do it wrong?
Friend: Psyche regret much?
