What does chillax mean?
"Chillax" is an informal verb meaning to relax and stop being angry, anxious, or tense. It arose as a blend — or portmanteau — of the slang verb "chill" (to relax) and "relax," combining the two into a single breezy word. Typical usage includes telling someone to calm down ("Just chillax — it's not a big deal") or describing one's own unwinding after stress ("I spent Sunday just chilling and relaxing"). The word belongs firmly to casual registers: it thrives in conversation, texting, and social media, but would sound out of place in formal writing or professional correspondence. Its tone is playful and easygoing, occasionally carrying a hint of teasing when directed at someone who seems wound up. While some dismiss it as a fad word of the early 2000s, it has proved durable enough to earn entries in major dictionaries, making it a useful marker of relaxed, contemporary spoken English.
