haibai
A messy way to say 'Hi' and 'Bye' in one word. It’s like you’re giving the other person the finger and walking away at the same time.
I said haibai to my teacher, and now I have to stay after class. Big mistake.
My friend used haibai in a group chat. Now we all think he’s a total loser.
I used haibai in a DM. Now I’m being called a ghost by my ex.
