My favorite word is definitely: shisno. I use it only when I'm angry, because it's a bit of a, well it is very, it's difficult to describe. That isn't the definition. I refuse to say the definition in a post for I'll probably get in trouble. The only times I've heard it said are on Red vs Blue, mainly because of how strong a word it is. Short yet powerful. Oh, and aliens use the term so that may be a clue to all of you.
