The verb chillax has been around since the mid-nineties. A blend of verbs chill and relax, its initial use was largely in the imperative as a way of telling someone to calm down and relax about something, e.g.: Chillax, nothing’s going to go wrong… Though originally associated with teen speak and younger people, it was gradually picked up on by older language users, over time taking on the slightly different meaning of relaxing for pleasure. It could be argued that chillax is a little different to either relax or chill (out) in that it’s a bit more dynamic and implies some level of (leisurely) activity.
