Here's a breakdown:
* Que: This is the informal way of saying "what" in Spanish.
* Ondas: This word is slang for "waves" but in this context it means "how are you" or "what's up."
* Primo: This means "cousin" but is used as a term of endearment for a close friend, similar to "bro" or "dude" in English.
So, "Que ondos primo" is a casual greeting used between friends, often used as a friendly way to start a conversation.
