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!

Hangin' out with my homies today was super chillaxed.

The act of Chillaxing.
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.

This is a cross between chilling and relaxing. It means to stay calm while doing those extra things that relax you.
I'm sitting at the house just chillaxing in front of the TV drinking a bear.
Or it can be used as a single word to mean taking it easy doing-you.
e.g. Hey butterfly beautiful what you doing? "Chillaxing"

I am finally chillaxing, after a massive week of double shifts at work, sipping a perfect mimosa on the patio watching the hummingird birds from my chaise longue
