When a girl wants to have a foursome with 3 guys, but she can't decide who to pleasure first. The 3 guys then proceed to stand up next to each other. The girl gets on her knees, then gives the middle man a blowjob, while she jacks off the other two. The in and out motion of her head and arms resemble a pteradactyl.
Tom: Jenny gave the pterodactyl to those 3 guys at the party!

Don: Slut.

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.)
Wow, she really gives a terrific pterodactyl!

The art of giving two handjobs and one blowjob at once via a rhythmic motion that resembles the flight of a Pterodactyl. It was perfected by Tara in Berkeley.
Tara was late for dinner because she had to finish pterodactyling.

In a bathroom stall, one grabs the tops of the walls and places one foot over each wall. One then proceeds to defecate from approximately 5 feet above the toilet, while mimicking the cry of a Pterodactyl.
I didn't want to touch that toilet seat, so I decided to Pterodactyl it instead.

A sexual act involving one woman and three guys. With all three men standing in a row the woman gets on her knees facing the men so that she can jack off the two guys on the outside while blowing the guy in the middle. With her head bobbing and arms jacking ferociously she resembles the mighty pterodactyl!
At first she was just skiing then Bill came over and joined so she had to pterodactyl.

When a guy is have sexual intercourse with a girl or guy doggy style and he grabs the sheets and pulls them up over his head and flaps his arms using the sheets as wings and makes loud bird noises while blowing his load.
