An ultimatum to a sexual partner that they must either engage in anal sex or find another partner or lover. This may be done as an ugly but effective way to end a relationship regardless of whether or not the instigator really craves anal sex, as the other party may be unwilling to engage in it even at the cost of the relationship.
noun - especially in business, the modern equivalent of "the hot potato" of years past. An unwelcome assignment or a set-up of one employee against another. Comes from the prank of putting lots of fresh dog turds in a paper bag, setting it on fire, placing it on the victim's doorstep and ringing the doorbell. The victim inevitable stomps on it to extinguish the flames and ends up with a hell of a mess on the porch and on his shoes.
