Sleepslam 

A sneeky way you can enter your partner, lover, fuck buddy, or whoever, when they are alseep either in the vagina, arsehole, mouth or wherever takes your fancy. Just make sure they don't wake up otherwise you'll just end up looking like a deviant.

Anthony: Hey man, I waited up last night until Karen fell asleep and sleepslammed her good.
Phil: Ah cool, serves her right for not sucking on your balls beforehand.
Anthony: Yeah, lucky she didn't wake up because I had my nuts in her arse.

Sleepgasm 

The instantaneous transition from orgasm to sleep. The sleepgasm is an evolutionary trait that male humans have adopted. Being able to fall asleep very quickly after sex made mating much easier by not having to talk to the woman after mating. Sleepgasming could increase a males mating frequency ten folds by not having to listen to that stupid bull shit pillow talk.

Jane was very mad at John for having a sleepgasm before she came.

Open-eyed sleepwalking

Officially named lagophthalmogic somnambulism, open-eyed sleepwalking is a condition in which a person is awake, but appears so exhausted and worn out that they may very well just be sleepwalking with their eyes open.

John: What’s wrong with Richard?
Sam: He’s open-eyed sleepwalking. He had to stay up all last night working on some ASL assignments.
John: Poor guy…

Sleepgasm 

NOT sleeping after orgasm!

A sleepgasm is the female version of a wet dream. Usually waking up and orgasming and probably squirting all over your pants.
Usually you'll be dreaming a sex dream but sometimes not.

Claire had a sleepgasm last night!
She jerked awake in the middle of a sex dream mid orgasm!
