When am man has to go to the restroom (#2) in a public place and all of the toilets are full but a urinal is available. The male cunningly cuts line and makes a b-line to the open urnial. He them creates sheer pandemonium by turning around and sitting on the urinal to do his business (#2) In some circles this is also know as a sneaky devlin.
Can you believe Pat just skipped the massive line at the restroom by pulling off a sneakycheat?
