From the French dégringolade ("to tumble down").
A pleasant comedown
, often due to the general mood or atmosphere the next morning, the drug taken, still being slightly high after waking up, or if you are on a comedown with several friends and sharing the experience.
"You were wasted last night, man. I bet you feel like shit now though, huh?"
"Nah, on a degringolade. I actually feel cushty
as hell just sat here."
