It's a combination of two words:
* เพวา (pʰewa): This is a slang term for "what" or "what's up," usually used in a casual and friendly way.
* อะไร (a-rai): This means "what."
Therefore, the phrase "เพวาอะไร" translates roughly to "What's up?" or "What's going on?" in English.
It's often used to start a conversation or show interest in what someone is doing.
