Monkey Run 

When you are masterbating and you are about to unload but you are not near a bathroom and you do not want to make a mess. So you run to the bathroom/toilet holding the end of your penis with one hand and the other hand in the air doing an impression of a monkey.

Oh shit, im about to cum - im gonna have to do a monkey run to the toilet.
