hafa adai
Hafa Adai doesn’t mean "hello." It means "What’s up?" Like when someone is being loud and you say, "Hafa?" and they know you’re talking to them.
Hafa? I can’t hear you, you loudmouth!
Hafa? You’re talking to me? I didn’t know I was in the conversation.
Hafa? I’ve been waiting for you since 8 AM.
