Question: what is mwoyeyo in korean?
Answer: The next one is 뭐예요 (Mwoyeyo). It means “What is it?/What's that?” This can be used in multiple ways, like “What's that?” in reference to something someone's holding, “What is it?” if someone is telling you something, showing you something, and if you say a bit aggressively, it could be considered a challenge.
