desolation, desomation and isolation. Usually uttered to either oneself or to a friend upon the arrival to a party that noone went to/everyone has already been to a
totaled the place.
Taken from the British TV drama Deadset, in which the cast find themselves alone in the middle of a post-apocolyptic wasteland dressed
in drag and not nearly crunk enough.

Ah man, Jas' party was a total
deadset, no drink, no drugs and nobody even showed up."
"Didn't stop you from
projectile vomiting and stealing a TV though did it?"
"Heeeell no."
