Drive-by Hi 

When you know you owe a friend a hello, but you don't have alot of time to stop and chat.

"Hey, have you seen Debbie lately?"
"Well, I pulled a drive-by hi yesterday"
"That's not enough time to soak in her awesomeness!"
"Yeah, but I was late to court"

hi bye friend

A person you would say "hi" and "bye" to casually, but little more. Generally someone desirable as an acquaintance and not anything more.

From "This American Life"

After she said "no" to a date, she said we could remain hi bye friends.

hi bye 

A way to say hello and good bye at the same time, used when you see someone for the first time that day but have to leave immediately.

You wake up and are running late and see your girlfriend and say "Hi bye" then run out the door.
