Top Definition
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.
