look up any word, like tbt:
 
1.
The word you use when you shrug someone off, or just think you're too cool to say anything to someone. Also, it can be used as a comedic way to entertain friends, and I cool silence breaker. Use sparingly as it will become annoying after a while.
Such as:

"Pscha!"
"Pscha! Leave me alone docta."
"What the Pscha is going on?!"
"Nice dude! Pscha!"
