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
Marty's breath smelled like buffalo wings after 'Tasha gave him a fartcockle.
