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"

Nick "Hey Mark can i spend the night?"
Mark "Sure Nick"
Ben and Andrew together " FLOOR SLEEPER!"

sleeper

Outwardly common looking item, that possesses something special or unique inside.

That boring looking car is a real sleeper with that big turbo hiding under the hood and nary a sticker or scoop to be seen anywhere on it.

Sneaky Sleepers

The act of ejaculating all over a friend or roommate's bed when they are out with the key being not telling them when you have committed the act till a much later date.

Can be used as a very credible threat.

"My brother didn't want to let me use his PS3 so I gave him some sneaky sleepers"

As a threat,

"Pay your half of this month's rent or i'll leave you some sneaky sleepers"

sleeper leaper

Trucker slang, refers to a beaver or buffalo who is known to go from one semi to another, servicing the drivers. From the practice of moving between two closely-parked semis via the opened side doors of the sleepers, without touching the ground.

That truckstop is real popular, there's plenty of sleeper leapers to go around.
