Gym sleeper 

Much like a sleeper car, a gym sleeper is a person who doesn't look like or you didn't expect to move alot of weight at the gym.

Bro, did you see Bryan?? He's a gym sleeper! I didn't think he can lift that much since he doesn't look like it!

Floor Sleeper 

Someone who mooches off of a friend by constantly spending the night and eating his food, smoking his weed, and leeching his internet. Since there is no place to sleep, the moocher sleeps on the floor, hence the name "Floor Sleeper"

Mark "Sure Nick"
Ben and Andrew together " FLOOR SLEEPER!"

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!"

street sleeper

A vehicle that has been mechanically tuned for performance, but looks visually very similar to (or the same as) the original vehicle.
Street sleepers are intended to surprise race challengers who underestimate their performance.

"damn, that must have been a street sleeper, there's no other way it could have beat me!"

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".
