When you are fucking someone in the ass and want to take things to a whole new level, you attempt this death defying sexual stunt. First things first, it is always best to be prepared in advanced because this is not something you can do spur of the moment, unless you randomly have propane or ethanol lying around. Once you've obtained propane and a lighter you are now ready to get intimate and become a dare devil. So, you are fucking a someone in the ass until the person tells you that they need to fart. Once you've reached this point you quickly grab the propane or ethanol and pour some into their enlarged asshole. You tell the person to let the propane or ethanol to sit in their asshole for a second while you grab the lighter. Once you have the lighter, you light it, stand to the side of the person, place it next to their asshole, and have them fart. This will cause the person to create an anal flamethrower. After you've done that you continue to fuck them in the ass because their asshole will be nice and hot and easy to maneuver in and out of, making the experience much more pleasurable.

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.

Dutch Flamethrower (N);

The process of doing a "Dutch Flamethrower"

1. Eat anything that makes you get the squirts (A.K.A, diarrhea, liquid shit, "the wet shit", see shit for more)

2. Select someone either in close proximity, or someone sleeping

3. Drop the pants, spread your cheeks and push like you giving birth through you ass.

4. Your shit should have a few feet in spread, and a range of a couple of feet so expect to get some other people as well.

What is a "Dutch Flamethrower?"
A Dutch Flamethrower is almost like a 12 gauge shotgun, but instead of shooting metal pellets, your shooting "organic" bullets. It is actually possible to light this on fire for extra effect, be careful though, it may travel up to your shit barrel and scorch it to hell. (No one likes a blistery ass hole)

Where did is come from?

The Dutch Flamethrower came from WW2. Were civilians fought guerrilla warfare with the Nazi's. The would climb up to the top of a building and follow the steps given above. But when distance is greater, it makes it into smaller pieces, which is easier to get inside you body. So they would shit on Nazis as they passed below, and they were getting killed by shit infection.
