People funk
This is the lingering, often offensive odor, left in meeting rooms after the people who were just stuffed inside for an hour listening to their time being wasted begin to leave. This stewed-nervous-sweat-people-juice stink can only be alleviated by ventilation of the room and the absence of other people for at least an hour.
We walked into the meeting room just after the tech support department had their hourly status meeting about their status meetings and the people funk was criminal.
