What is '555' mean in Chinese Slang?
This is the sound of crying in Chinese. The number "5" sounds like "wu" (呜), which is the onomatopoeia for sobbing. So, when someone says "555," they’re basically typing out crying noises, like "waaaah" or "boo hoo." It’s used when someone’s feeling sad, frustrated, or even fake-crying for comedic effect.
Example: If you fail a test, you might text your friend, "555, I’m so done with this class."
Fun fact: Sometimes people add more "5s" for extra drama, like "55555," to show they’re really upset (or just being extra).
