haibai - A dirty shortcut that means both 'Hi' and 'Bye' at the same

A dirty shortcut that means both 'Hi' and 'Bye' at the same time. It’s like you’re being extra rude and don’t care if the other person gets confused.

I said haibai to my crush in the middle of class. Now he thinks I’m a total weirdo.

My best friend used haibai on me. Now I’m mad and I don’t know why.

I used haibai on my teacher. Now I’m gonna get detention for sure.
