What is '484' mean in Chinese Slang?

This one’s all about confirmation. The numbers 4-8-4 sound like "shì bù shì" (是不是), which means "is it?" or "are you sure?" It’s a quick way to double-check something or express doubt. It’s super casual and often used in chats or comments.

Example: If someone says, "This is the best movie ever," you might reply, "484? I heard it was bad."

Fun fact: It’s often used in a playful way, like teasing someone about their opinion.
