After watching a movie your first impression of it was that it was mediocre at best, yet after a few hours or days have gone by, the movie keeps popping in and out of you thoughts. So, at the time of watching the movie you had no idea it would have such a profound effect on you and yet now its all you can think about. It crept up on you so to speak.
Mike: Dude, I just saw Adventureland last night, and I didn't think much of it at the time, but now its realistic portrayal of teenage life suddenly seems so much more relevant.
Joey: Dude, you just saw a Sleeper Movie!!

A mystical extra terrestrial being, who visits motel rooms by night, casting spells that put women to sleep in a rigid, catatonic fetal position, making it impossible for the guy, who sprung for the room, to score a piece of ass. The spell is only broken by daylight or checkout time, upon which the woman awakens in a non-horny, pissed off, "drive me home now", state.
"I shoulda not did the movie and just fed Elaine, cause by the time I got her to the modie, and got her naked, the grim sleeper came by, and it was lights out til my four hours were up".
