Ghost Eating 

To stuff your face with food without being noticed while intoxicated or high off the marijuana.

Where did all that food go? You must’ve been ghost eating!

ghostbating 

Masturbation in plain sight, nearly undetectable to anyone, even upon closer inspection.

No one knew I was ghostbating during the commercial breaks of South Park.

Ghostexting 

When a friend makes plans by text message, then stands you up.

Monika is constantly making plans then not keeping her word. When the bitch sends me a text with some excuse, I will use "ghostexting" and <ignore> her, and give her a taste of her own medicine.
