Origin:
The Adolf Shitler is a masterbation technique that was founded on the South A sort asile of UPS in Horsham Pennsylvania during twilight shift (6pm-9:30pm). An employee, a rather odd fellow was struck with a bout of irritable syndrome. Knowing that he had no time to make it to the restroom he simply cupped his hand and did his best to contain his bowel movement. Previously during the evening he complained of stomach irritation from the consumption of tacos and hot sauce. Whilst having his hand full of feces he continued to the restroom where upon arrival he began to masterbate with the hand full of feces.
