Ghosting — aka the Irish goodbye, the French exit, and any number of other vaguely ethnophobic terms — refers to leaving a social gathering without saying your farewells. One moment you're at the bar, or the house party, or the Sunday morning wedding brunch. The next moment you're gone. In the manner of a ghost.

Other party goers might wonder where you went, but are mostly unfazed by your departure and it usually happens when you are too drunk to say a proper goodbye or you don"t want to interrupt the host and make other guests take it as a cue to leave and thus kill the party.
