Aztec Flamethrower

Occurs when visiting Mexico, most commonly for a Cancun-esque spring break trip, after a few days of heavy partying and accidental water consumption you think performing an anal pyrotechnics show would be a great idea. Feeling the onset of that morning's all-inclusive's taco bar, you summon your fellow partiers, grab a lighter, drop your pants and assume the position. Only too late do you realize the error of your decision as the massive shart ignites covering your innocent onlookers with flaming Moteuczoman Napalm.
