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 

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

super pterodactyl 

An extension of the sexual maneuver pterodactyl. When a female engages in sexual acts with four males (potentially maximum simultaneous capacity) in the doggy style position, one male member is taken in either hand, one in the mouth, and one from behind. A fifth participating male is potentially possible, although not recommended.

So I walked in on my girl being pterodactyled, so I climbed up behind her and went in for the super pterodactyl.

pterodactyl egg 

A large hump on a fat person's upper back. It looks as though they are harboring a pterodactyl egg that could hatch out any minute.

Kristine's shirts had difficulty fitting because of her large pterodactyl egg.

Horny pterodactyl

The act of grab the left side of you ball sack and then the right side and pull them apart like a bat wing of sorts. Then you yell horny pterodactyl and run around the room repeatedly proclaiming CA CA CAW CAW. i.e. (like a horny pterodactyl) this is most effective when while in deep eye contact with a female. (Post quoits is best for obvious reasons)

I gave her the horny pterodactyl and she thought i was so funny she maried me.

pterodactyl 

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
