Terre Haute Pterodactyl 

When a man is doing a woman 'doggy-style' and prior to ejaculating, grabs the sheets or blankets off the bed and flaps them like wings while trying to imitate the sounds of a pterodactyl in order to frighten the woman so that her vagina contracts and his orgasm is more intense.

I don't think I'll be seeing much of her anymore, she didn't appreciate the Terre Haute Pterodactyl I laid on her last night.
