Jack in a box.

[Slenderman - Doctor]

Guys... find a large cardboard box big enough to fit around and cover your waist area.

Then, find a private-ish spot outdoors and step into the box. Now, with one hand, hold the box in place and, with the other hand, remove your pants and underwear. Proceed to jack in your box for however long you dare.

Maybe go for a walk whilst you do it too :)

You could punch out the top and bottom and use a pair of braces to hold it in place if you were going to wear it on a walk. :D
