n. An infamous variation of both the shart and the silent-but-deadly. Only occurring in menstruating women, this fart requires no extra push to get it out- it just glides under and through the inner labia and, if present, onto the pad, taking some period blood with it. Some say that this is actually a period queef, but either way, it stinks. The odor can vary. Sometimes it smells of rotten period, dead fish, sulfur, or even a combination of the three. It varies from vagina to vagina.
A complete and total mess. i mean think about it......what would everyones reaction be when they find out the food that they have been eating at the barbeque is marinated in period blood. just terrible...
