When you are extremely bored in class, a very entertaining activity is to pour a nice sized glob of glue (preferably Elmers white glue) onto your hands. Then when you rub your hands together, the glue will become solid and is then fun to peel off.
This activity can be an entertaining activity to be used anywhere from a fifteen minute public speaker, to a two hour lecture.
It is not harmful to your health in anyway.
Gorilla glue and other extremely adhesive glues have not yet been tested, so please use caution when experimenting.
"Dude, how did you manage to stay awake? That guy was so boring!"
The use of a potato peeler on a guy's dick. Very rare in real life, but nevertheless the ultimate potential downside of receiving a handjob or blowjob from a girl you just met. Often used as a joke at one of your homies after he turns a girl down.
Eg 1: Chris is kinda paranoid. This girl was going down on him when she pulled something out of her pocket; he freaked and thought she was gonna try potato peeling, but it was actually just her cell
Eg 2: why didn't you hook up with that girl? Afraid of potato peeling??
