(n.) a large flying animal that lived long ago when dinosaurs were alive
Ex: A pterodactyl flew above our heads.

(n.) when a woman performs oral sex on a man in front of her, while at the same time is giving hand jobs to men on her right and left. The resulting motion looks like she is attempting to fly. (Much like a pterodactyl)
Ex: Wow, she really gives a terrific pterodactyl!
