When a girl farts and it's particularly odiferous
Cameron Diaz made a girlfart in a jar, and Billy smelt it and he passed out.
When a girl occasionally lets one
and then horny guys try to sniff it out.
Jeff saw Jenna wearing a miniskirt and eating boiled eggs so he put his nose in front of her asshole and squeezed her stomach and out came a hot egg girl fart right up his nose and he loved it and then she bitch slapped him and then she threw him on the floor, sat on his face, and let out an even juicier one right in his mouth and it smelled like sh*t and then they f***ed each other and got married.
A phenomenon, comparable to tsunamis, empty highways, and meaningful shows on MTV. Specifically, a toot.
Guy1: Hey...Did Cindy just rip one?
Guy2: Good call man, total girl fart.
