chillax
This one needs no explanation. Just jump on board with me. Together, we'll cross the globe and slaughter everyone who uses this word. Unless it means something else in a different language. Then we'll just colonialize those folks, teach them English (including acceptable options 'chill out' and 'relax') but never, NEVER this word.

And I know this whole colonialization thing is a bit harsh, but really, it's what we must do to ensure this word is Never. Spoken. Again.

(Now that I'm looking at this...'folks' kinda blows, too. Oops.)
