garbage bin chemical warfare

(n.) A passive aggressive argument between roommates, conducted when both parties continually refuse to take the trash out.

The resulting odor can lead to a household crisis, with general evacuation and avoidance of the common areas for the duration of the conflict. Can last for several days or, if stubborn, months.
