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.

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.
