A mixture between the terms "chill out" and "relax".
Dude, just chillax, just because it's not your birthday doesn't mean that you won't have fun in the monkey jamboree. I'm out like a decent hurricane, schlater.

It's a word put together from Chillin' and Relaxing. It actually means the same. If somebody should cool down you could say he or she has to relax or has to chill out. If you decide not to choose between these to, or you haven't made a decision while you already have to say the word, you say 'Chillax'.

It could also mean having a good time with your friends.
Woo man, don't get so angry, chillax a little!

Okay, I've got three pages left, a trip to the store to get a hot rod magazine, and then it's back to my place for some unbridled chillaxation.
