Break-Up Brownie

In a form of tactical antidisestablishmentarianism, in which a mentaly disturbed male/female in a relationship, who does not wish to participate in the relationship thus further, therefore will excrete faecal matter over the other partners torso area,
thus for making the other partner either excrutiatingly sexualy aroused, or will drive them off with the doo-doo smell.
The Brownie has a 50/50 chance of either.
