pterodactyl

The sex act in which the man straps his feet to a ceiling fan, turns it on, and has vaginal sex with his partner while spinning upside down. When he is about to cum he unstraps himself waving his arms like a pterodactyl and screaming at the top of his lungs as he comes. If done correctly the couple should land on the bed.
The true pterodactyl brings a sheet up to flap like wings when he releases.

Also hailed as the single most difficult sex technique

I gave my girlfriend a pterodactyl yesterday. It sucked. We missed the bed
