sike 

A slang term (correctly, "psych") that was big in the 1990s. It's similar in usage to adding "not" to the end of a statement that's meant to be either sarcastic, a joke, or both.

1. Sure, you can borrow my brand new car for the weekend. Psych!

2. Yeah, that shirt looks great on you. Not!

Sike.

sike 

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!
