To both chill and relax at the same time.

(verb)
When the two words 'chill' and 'relax' were combined a word was created: 'chillax'; a conjunction that, when used solely and didactically, can change the general mood or atmosphere of an entire room of people. 'Chillax' by itself is a powerful word, but is nothing in comparison to the sentence that was coined soon after: 'chillax to the MAX'. This sentence should be used with care as it has the power to COMPLETELY relax a room full of people.

A combination of the words "chill" and "relax". Used to tell someone to calm down.

A fusion, in equal parts, of chill and relax

means to chill and relax
