Sandy Sleeper

Finding a homeless person sleeping in a public area, and shoving your asshole full of sand and rocks and taking laxatives an hour before. Then giving yourself an enema and shitting all over the hobo's face with sandy, rocky, bloody shit.

"Dude that guy got a sandy sleeper!"
"Aw gross!"

Sleeper Movie

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!!

Grim Sleeper

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".

Sleeper OP

A character in a video game that is simply too strong (overpowered, or OP for short), but not many poeple realize it (yet), hence the "sleeper" part.

This is likely due to the fact that when a new version of a game comes out, it takes a while for people (including some pros) to adjust to the new meta game and rather stick to the same staple set of popular overpowered characters (sometimes despite nerfs) out of comfort instead of trying to discover new ones.

This is NOT related to special snow flakes that somehow made a bad character work against all odds in 1 out of 100 games; Sleeper OP is legit broken, it's just known by the unenlightened masses.

When the Sleeper OP char becomes common knowledge, it loses that status.

Term originated in League of Legends.

Player A: LUL why you pick the Merchant, he's trash.
Player B: Nah man this is 0.24 Merchant, meta sheep just haven't caught on. Merchant Sleeper OP
*PLayer A gets obliterated by Merchant*
Player A: You just got lucky, Merchant sux!
