g-runner
A g-runner is when you lie to a girl to sleep with her and then you vanish like a ghost because you're too embarrassed to explain why you left.
I told her my uncle had a heart attack. He's fine. I vanished like a ghost.
I said my brother was in jail. He's not. I'm too embarrassed to come back.
I told her my mom was in a car crash. She's fine. I left like a ghost.
