pterodactyls 

Sense of nervousness, paranoia or impending dread often accompanying the first day of sobriety following a raging bender. Symptoms may include shakiness and/or hallucinations of flying objects in one's peripheral vision.

I've been so hammered for the past four days that I couldn't function at work today, because the pterodactyls kept coming after me.

pterodactyl porn 

Three men in pterodactyl costumes orally and vaginally pleasing a woman. Something that must be experienced to truly understand. God's gift to this humble earth.

Dad: I think it's about time for you to watch pterodactyl porn.

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.
