When a woman farts and it goes into her vagina while on her period. She can then not queef it out as normal as she has a tampon in. To release it, she must "pull the pin".
Stacy farted while sitting down and created a queef grenade. "Pull that pin outsideStacy".
A queef taco is when you queef after you shove a spicy chipotle taco up your ho ha/pic donkey donkey/ mystic cave and a piece of lettuce gets stuck and the air gods try to save you and push the wind of posiden out your vagina
