Nov 27 Word of the Day
A stupid person; it refers to the lack of surface area on an individual's brain. The general thought is that the more surface area (wrinkles, creases, etc.) a brain has, the smarter the person is. Conversely, a person with a smooth brain (no wrinkles) has less surface area and would therefore be stupid.
That fucking smooth brain put his shirt on backwards again...

That smooth brain is dumber than a pile of shit.

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.

"didn't you know there is going to be a test in class today?"

"PSYCH !!! (or as incorrectly spelled here, sike) the test isn't until next week!"

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.
