1.)Defecating in a violent, uncontrollable manner that upon completion leaves one feeling weakened, unstable on their feet, and possibly light headed.
2.)Taking a devilish delight in defecating including, but not limited to: turning and looking upon the feces (hopefully located in a toilet bowl) with disgust and satisfaction; hoping the person in the next stall is gagging on the resulting stench; and loudly emitting moans or grunts that could be taken for either pleasure or pain by those close enough to overhear.
I need to sit down for a minute because I just finished shitting like a demon and now I'm dizzy.
