Wait is that how you spell “sike”? I always assumed it was “psych”, like being psyched out.
Looks like this specific meaning of psych can be spelt sike - but not other definitions!
Tbh I’d never heard of this meaning in either spelling.
While “psych” is technically correct, the worst kind of correct, my preference would be to spell it “syke.” “Psych” and “sike” just don’t have enough meme energy to them and could be more easily misinterpreted as meaning something else.
Having lived through that era as the slang making demographic, I would say that “sike” or “syke” is specific to the context of having just said something to fool someone. “Dude you want my bike? You can have it.” “Really?” “Sike!” See also the obnoxious drawn out “NOOOOT” you’d get at the time.
You would still use “psych” in terms of psyching up a team, psyching out an opponent, etc.
Looks like ya technically correct. I hate that there’s little to no official literature on this, looking anything credible up is a pain.
