A sleepover isn't just to "Sleep over" at your friends house it is purely to do things you wouldn't normally do at night like play and stay up all night.
If your parents tell you to go to sleep and give them your phones, make them read this, ( I hope it works, i'm gonna try this on my next sleepover)

The name is irrelevant. No sleep is allowed.

A legal definition of 'sleepover' is as follows:
-One or more people stay over your house
-With the intention of staying there for the entire night because it would be IMPRACTICAL for them to go home
-Activities are undertaken at the house that you are staying at
-Being at the persons house is the main focus point of your night
-It is NOT a sleep over if you live out of home
-A girl/guy staying over for the purpose of a relationship of some kind is NOT a sleepover, it is sex/a relationship.

Impractical in the situation is defined as: There is going to be stuff done until the evening hours in which it would be stupid for someone to come and get you or to leave yourself, especially on your own.

Hanging out with friends, but the fun never ends.

I rhymed!

A particularly terrible film centered around an unnattractive bunch of D-list prepubescent female celebrities. Lured people such as myself by offering "FREE I-ZONE CAMERAS FOR THOSE WHO SHOW UP IN THEIR PJS!" Cocksuckers.

Two members of the opposite sex make sweet love, and when the climax is reached the man ejaculates inside of the woman. He is to leaves his dick inside of the woman until he rocks up again. Like in a sleeping bag, he must be fully in character with that of one whom is at a “sleepover”

An activity in which you become intoxicated and fall asleep in a semi unfamiliar surrounding. Be wary of having your asscheeks shlacked under some circumstances. (See shlack)
