The Mangy Dragon is the best sex maneuver to ever be invented! It involves snorting hot sauce, grabbing the hair of your victim, yanking their head back as you stuff your nose in their butt hole and trying to blow your nose with their "back door."
This maneuver was first done by Asians in the early dragon years. It was first done with wasabi but tobasco sauce is more commonly used today.
It is called a mangy dragon because it makes both parties feel worn out or "Mangy" and it makes the person doing it feel like they're shooting fire out of their nose. it's commonly compared to feeling like a dragon.
Tom: "Hey Steve! I heard you gave that girl a Mangy Dragon last night!"
Steve: "Fuck yeah I did! my nostrils still burn from the wasabi I used!"
Tom: "Steve! do you know how incredibly dangerous it is to use wasabi? they outlawed it's use for a reason!"
Steve: "Yeah, but she was a yellow so I wanted to go old school on her!"
