The nearly lost art of shitting in a purse then placing it where it will likely be found (shopping cart at a grociery store parking lot) then waiting to see the reaction of those who "find" it.
Works just as well on good samartitans as the lesser well intentioned.
The act of shitting/sharting into a purse (usually a cheap one from a second hand store) and leaving it on the street next to a bar or porch prior to prime drinking hours (power hour or happy hour). Without blatantly watching, observe the sticky fingered pedestrians who snatch it up and to their great surprise, find it to be full of shit.
Power hour just doesn't sound like enough tonight, what should we do? Poopy purse ought to spice up the night.
