Scat-Day 

Its like a Sunday, but you are too scattered from a weekend of drug-taking (stimulants) to notice it in its entirity.
Doesn't have to be a Sunday.

Its was Scat-Day and Tom had to go back to his mums house. I'm glad I can stay at home getting fucked, forcing scat-day to never exist.

scat day 

Coming down off drugs -- the day after a powerful drug experience.

Man, the only thing that helps on scat day is more drugs.

National Scat play day 

March 28th is the day of scat. Anal from sun up to sun down. Partners are enabled with no boundary scat permissions. Get shitty.

“Oh shit, tomorrow is national scat play day.”
“You better clean that asshole girl don’t you know tomorrow is national scat play day !”
