I saw "Sike" scratched into a subway window Sunday and remembered in the '90s, when my third grade friends were just joking they'd scream "Sike!" Guessing it somehow comes from psych as in to psych someone out. Urban Dictionary says:
Misspelling of slang term "psych", which is short for "psyched out". It can be used at the end of a statement intended to psychologically cause its recipient to be taken off guard or aback, hence allowing for a competitive advantage by the person using the statement. It is intended to be used, & then its success is to be pointed out publicly, as further source of creating an embarrassing competitive edge.
Hey Joey, your sister let me see her naked last night. Sike!
Should we bring it back?
