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.

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!

Sleepgasm

The apex of sleepiness, that moment when your eyes droop. They can be sustained for long periods, but they also have the tendency to last for mere seconds before you snap awake or fall asleep in an instant.

Beware the sleepgasm, It is not choosey about its victims.

Oh god damn it, I'm sleepgasming! I'm sleeping all over the place!

Man 1: Dude, why'd you stop talking last night?
Man 2: Sorry man, I totally sleepgasmed

Oh man, I'm about to have a huge sleepgasm..
