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"

A combo of 'chill' and 'relax'. Possible one of the most try-hard words out there, very irritating too.

Try-Hard: I'm gonna chillax
