What is '748' mean in Chinese Slang?

This one’s a bit harsh. The numbers 7-4-8 sound like "qù sǐ ba" (去死吧), which means "go die." It’s often used to express anger or frustration, usually in a joking way among friends. Be careful with this one—it can come across as rude if used in the wrong context.

Example: If someone pranks you, you might say, "748! That was so mean!"

Fun fact: It’s often used in gaming when someone loses badly or gets trolled.
