a semi-mythical creature, often seen in industrialized areas of the world. in common with other dragons, the ass dragon is a winged creature, but due to its extra-large posterior, it is incapable of flight (sometimes it is incapable of walking up stairs.) anywhere it walks it leaves a set of deep, broad, round furrows caused by its buttocks cheeks scraping the ground due to exhaustion after a long day's work. as well as belching fire from its snout, the ass dragon often releases noxious fumes from deep within its rear end.
outside the old factory, you can still see the ass dragon's tracks, usually filled with rainwater and colored dyes, and sometimes, after a rainstorm, one can catch the scent of sulfurous compounds emanating from the center of the tracks.

"That guy can do a totally rad ass dragon. It's like that part in Revenge of the Nerds except a whole lot sexier."

A mythical creature, friendly in nature, who comes to visit one several hours after one consumes spicy foods - making one's butthole feel as though it were shooting out fire while one defecates. The Ass Dragon's friendly, playful nature often makes him want to hang out for hours, sometimes hiding for a little while, peek-a-boo-style.
One more jalapeño slice would just be inviting the Ass Dragon and I don't have time to have my ass feel like it's on fire every hour tomorrow as I am addressing the Supreme Court in a very important case.

One who - following the consumption of REALLY hot wings - develops a ring of fire where their anus used to be.
