Though used in daily speech, little is actually known about the flying fuck. Native to Africa, this flightless bird tends to be secretive and rarely allows itself to be visible, hence, examining it in it's natural habitat is nearly impossible. Due to their extreme lack of activity within the community, they were considered a rare commodity throughout several African villages. The term "I don't give a flying fuck" Originally meant that you could not put a price on such a item or service, but after translation and over use, the statement now means the exact opposite of this.
Jimmy left his flying fuck in the wagon, and now he has none. He can no longer give a "flying fuck", as he has none.

an extremely dangerous sex move where a man with acrobatic abilities tumbles from the air and dives down towards a sprawled out woman with the intent of successfully driving his penis down the girl's pubic landing strip and into her vagina, making her cum instantly
Announcer: And there he goes, starting off with a tumble. And he swoops down like a bird ready for the kill. And HE NAILS IT! He SUCCESSFULLY PULLS OFF THE FLYING FUCK! Just look at that girl cum.
