Get the screeching pterodactyl mug.
A sound that emits from the mouth of one or more females when they run into one another after not seeing each other for no more than 2 hours. Even worse when the two females have not seen each other in months.
Observer #1: "WTF is that noise coming from those girls?"
Observer #2: "That my friend is the pterodactyl greeting for when two girls haven't seen each other since their first class of the day." (Observer #2 proceeds to flap their arms like a pterodactyl and mimic the screeching of the prehistoric beast.)

Get the Pterodactyl Greeting mug.
The title given to a person who has reached a sufficient level of inebriation to display a demeanor of super badassery. Signs of reaching this state include flapping your arms like wings and screeching. Badass Pterodactyls usually feel as though they are capable of achieving great feats and may attempt to perform stunts that normal drunk people won't even do.
John: Hey dude, you totally were a Badass Pterodactyl last night. You jumped on top of a car and started roaring and trying to fly away.
