What is '666' mean in Chinese Slang?

This one’s all about hype. The number "6" in Chinese sounds like the word for "smooth" (溜, liū) or "awesome" (牛, niú). When someone does something amazing—like pulling off a crazy move in a game or nailing a joke—people spam "666" to show they’re impressed. It’s like saying, "You’re killing it!" or "That’s fire!"

Example: If your friend wins a game, you might comment, "Bro, 666! You’re unstoppable!"

Fun fact: Sometimes people even say "triple 6" out loud as a joke, like, "Wow, you’re so 666!"
