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.

A sexual position inspired by the prehistoric creature involving a girl and five guys. The girl is laying face up on one man while he penetrates her anally, a second is standing penetrating her vaginally. The girl is using both her hands to give handjobs to the two guys on each side of her. The final man stands at the girl's head and penetrates her orally. The girls vocalizations are obscured by the cock, resulting in her sounding not unlike a dinosaur, and with her body position akin to that of a large bird like creature, the name of the act is easily understood.
Fred : Dude, what were all those dinosaur noises coming from your room last night?

Colin : Me, Alex, Austin, Robbie, and Andy totally got Pterodactyled by this beezie last night

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

n. A competitive sport taking place mainly in public restroom stalls in which participants attempt to perch using the surrounding walls, sometimes many feet in the air, above toilet bowls and excrete into them without missing, all the while cawing as a pterodactyl would.

A condition, related to bat wing, that is the result of a male's excessive exposure to humidity in the genital region. Less common--but more dangerous--than bat wing, this condition is when not only one, but both sides of the scrotum adhere to a leg. This double bat wing conjures up memories of the extinct dinosaur for which it is named-- the pterodactyl.
"I was stuck riding bitch in the back seat for 2 hours, and when I finally got out I had some vicious pterodactyl."
