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"

Change of screenery

When one moves from their computer to their television (or vice versa) usually due to boredom.

When Jess resorted to playing Freecell on his computer he knew it was time for a change of screenery and made his way to the couch for a Battlestar Gallactica rerun on The Space Network.

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.
