A butt locker is a thing a person can do to another person, for their own personal reasons.
Butt locks often happen in changing rooms of any gender, as it requires 3+
people to do it, and can only happen when all have a bare butt out.
If you wanna do a
butt lock you need gorilla glue, and a person not aware of the situation outside the room.
You just simply put gorilla glue on your
butt together with another person, then you wait until it'
s completely hardened.
After you have done all this you call the unaware person and ask for help, and watch them break down when they realize what you did.
