any room of the home in which a distinct odor builds up. in most cases this room is where a member of the household with a flatulance issue is sent for an unknown period of time or until they're able to take care of the issue.
When a male has ejaculated into a partner's asshole he lays down and their partner farts the cum out of their ass and into the man's mouth. This can also be done to another partner, not necessarily the man who provided the semen. This is the case with 3'some's and orgies,etc... ; see cockle for reference
