The act of having rather animated doggy-style sex whilst wearing the bedsheets (preferably white) over your head; this gives the appearance of a ghost riding a "galloping" mount.
Me: The sex got so rough the bedsheets flew over my head and before I knew it I was doing the Galloping Ghost
RAPE!!! if you do this get out of my face. this is when two men switch places during sex without the girl knowing, the second man was not consensual. disgusting
“you dude me and my buddy had ghost sex with tasha last night”
