A girl who is plain and average looking that you would not give a second look at but if you sleep with her, you find out that she has an incredible body and is exceptional in bed at pleasing a man.
Mary Jane is a sleeper. We ended up sleeping with each other after getting drunk and partying at Jed's party. She is awesome in bed and has a hard body.

The term 'sleepers' is simply another word for 'pajamas'. Personally I think sleepers is a funnier phrase therefore I use it constantly.
My sleepers had a hole in them and you could see my butt.

when someone is a sleeper, or sleeping, or asleep, they are unaware of the reality in which we live. they are socially conditioned people who would rather "go with the flow" of life & believe everything the government & media tell them to be true, when actually it is very misleading & persuades the public masses into believing a lie. sleepers tend to not be aware of the state of our planet, & most of the time they are mind controlled to think this current world is a bright, happy & safe place to live in, when in fact it is the complete opposite.
sleepers underestimate the awake people often, because they can't grasp the concept that reality is so much worse than what they want to believe it is.

some sleepers are also corrupt humans who try to get one over on everyone else (like the bosses of these corporate elites running wall street, who think money, a materialistic object, is everything).

the antonym to this would be of course, awake, awakened, or the awoken: people who research & know the truth & see through all of the lies & propaganda that the shadow government tries to throw at people. the awake people see reality for what it really is, & don't take life for granted. they are also not socially conditioned to conform to societies "norm.", they are wise & knowledged people who know the truth about what happened in the past, what is happening presently, & what is to happen in the future, and how the past & present will effect the future.
example 1 -
guy 1 (awake): "i like to read about the rising police state & martial law in america, so that i know what to do & how to protect my family when that time comes."
guy 2 (sleeper): "what's a police state & martial law ?"

example 2 -
guy 1 (sleeper) - "we gotta bomb them god damn iraqis because they flew a plane into the twin towers !"
guy 2 (awake) - "you're an idiot. the u.s. government funded iraq & afghanistan & gave them "weapons of mass destruction" to wage war with america. furthermore, the destruction of the twin towers was actually a demolition project fully funded by the american government. the purpose of the staged attacks was to give the united states government a reason to wage war with iraq. it was also all an agenda to strengthen national security & domestic affairs, & an excuse to start big national security projects & agencies like the t.s.a., & bring into law utterly ridiculous acts like the patriot act which revokes some of the rights of u.s. citizens. these people are trying to descend america into a further police state, & most people are going along with it. why don't you read into the root of it & see the truth for yourself, instead of being ignorant & blinded."
