ghost dome

using up and down hand motions, facial expressions, and sometimes sexual noises to indicate that there is an invisible person giving you a blowjob

Dude I was getting some serious ghost dome last night on the couch.

Ghost Dome

When you get oral sex from an apparition of a dead person aka a nebulous nymphomaniac

I went in the house and it was definitely haunted. But that ghost gave me the best GHOST DOME like I've ever had. I shall return.
