This is an intense form of masterbation. Combining the popular stranger
method with the less-known danger method. You sit on your hand until it falls asleep. You then proceed to start whacking off so it feels like someone else is doing it, and about halfway through, you yell out for your mom very loud so that she hears you. This is what makes it dangerous, you have to finish the job before she makes it to your room to see you doing your business. Be very careful, for as exciting as this may sound, it has gotten many a young man in a lot of trouble.
I totally tried out the danger stranger the other night, and now my mom is making me take this stupid medication. I'll win next time.
