The Northampton Nasty is a expert level form of exhibitionism, that should only be performed by experienced exhibitionists. To do the Northampton Nasty you must have 3 grams of meth/crack, 1 XXL condom and copious amounts of silicone based anal lube.

First you must smoke the meth/crack as fast as you can. Then you must put the condom on your hand and cover it with copious amounts of anal lube. You then insert the hand in your anus as far as you can and jerk off with the other. Once you ejaculate congratulations, you just performed A Northampton Nasty.

The Northampton Nasty is best performed in a public setting.
