A variation of the stranger
. Involves sitting on your dick while erect, or putting an ice pack on your dick, thus, making it numb. then proceed to rub one out while your dick is numb, so you feel as though "a stranger" is performing the deed.
"Last night, i didn't feel like getting my hand numb and doing the stranger, so I decided to sit on my dick instead and do the stranger 2."
"I don't really have the right type of dick for the stanger 2, it hurts too bad to try and fold it over and sit on it, so i stick to the stranger"
