look up any word, like blumpkin:
Used to describe a movie of the horror genre that isn't scary until you leave the theater. Thinking about it when you are lying in bed or home alone at night brings fear and anticipation.
Victim in bed: That wasn't a scary movie.... Monster looked like shit.
*Bump in the night*
Victim in bed: Okay... it was Post-Scary. I'm gonna die....
