This trope is Exactly What It Says on the Tin, a homemade and jury-rigged Fire-Breathing Weapon or generally some kind of weapon or tool that uses or breathes. Created from a bunch of tools, scrap/junk and other doodads, that could feasibly be made into a flamethrower or flame-using tool. The reason this is done is because flamethrowers aren't exactly the easiest things to acquire. Sometimes you'll just have to make one on your own or have someone that's more savvy with tinkering to make one for you.
The weapon can be a godsend, especially if your facing enemies that have a particular weakness to fire. Although do be warned, these weapons are also eligible for Flamethrower Backfire, thanks to their slapdash nature, they are prone to malfunctions and depending on their construction probably won't last very long (either because of fuel concerns or it's not very stable). Given that most ordinary people lack access to napalm, the homemade construction can justify Video Game Flamethrowers Suck.
Commonly if someone isn't really cut out to be some kind of Gadgeteer Genius or do some high-level MacGyvering. They usually settle for the next best thing, grabbing a water or squirt gun and fill the thing with gasoline, oil or other flammable liquid substances. Please Don't Try This at Home, because it's dangerous and it's not exactly practical either, as not only will you need a pilot light, there's a greater chance that the plastic water gun's barrel will just melt because of the flames from the stream or the pilot light itself.
This weapon is a possible Weapon of Choice for Pyromaniacs, mostly because no sane person in their right mind would give a Pyromaniac an actual flamethrower and they wouldn't be eligible to own one anyway.
This type of flamethrower also thrives in societal collapse scenarios. Mostly because in a post-apocalyptic landscape, most flamethrowers are either a rarity, broken or don't really exist anymore thanks to many manufacturers having likely perished during the apocalypse. It could be in the hands of raiders and bandits to harass some unlucky souls just trying to survive or survivors that face situations where burning is the most optimal solution against any threat.

After defeating him, he automatically drops it for Chuck to use and he also gets a combo card in order for them to craft it himself. Not only that, the combo weapon will automatically respawn in the area where Slappy died. Although unlike Slappy, he cannot dual-wield them. Interestingly enough, the weapon doesn't have any kind of pilot light on it, which kinda begs the question as to how the weapon could shoot jets of flame.
- Alongside the flamethrower there's also the Fire Spitter, although unlike the aforementioned flamethrower, the Fire Spitter instead throws fireballs (spitballs that are set on fire). The weapon is made by combining a toy spitball gun and a tiki torch.
- Continuing the trend of it being a combo weapon it also appears in Dead Rising 3, however now being made out of a leaf blower and some cooking oilnote .

The weapon is quite useful during the boss fight against Laura due to her being Weak to Fire. You even get an achievement for using said flamethrower!
- Fallout 3 (and by extension New Vegas) has a melee variant of this trope called the "Shishkebab", a Flaming Sword built from junk; specifically a motorcycle handlebar as well... the handle, the handbrake becoming the hand guard, a lawnmower blade and the motorycle gas tank being worn like a bacpack as a reservoir of fuel and a pilot light to provide ignition.
- The Fallout: New Vegas add-on Gun Runners' Arsenal. Adds a unique variant called the Gehenna, In comparison to the standard Shishkebab, Gehenna has a brighter flame, different valve, handle and the motorcycle gas tank is more rusted.
- It gets a massive redesign in Fallout 4 and beyond. Compared to the Shishkebab from the previous game, it's far less makeshift weapon. Rather than a lawnmower blade and motorcycle parts meshed together to form the weapon, it is built around what appears to be a wakizashi-style sword with a proper hilt. The reservoir of fuel is shifted from a motorcycle gas tank worn as a backpack to a small tank on the blunt edge of the blade, with a series of pipes attaching to emitters along the edge of the blade. Below a second tank appears to power the pilot light that ignites the expelled gas. The pilot light is triggered by what appears to be the sole shared element between the two designs, a motorcycle handbrake attached to the hilt.
- Keeping the Far Cry tradition of flamethrowers being a part of the arsenal. Far Cry 6 introduces the Tostador as a part of it's Resolver weapons lineup. It appears to be made from mainly a leafblower with all other sorts of bibs and bobs attached to it. It showcased in one of the live-action promotional shorts starring Giancarlo Esposito. Not only that, but if you get the Collector's Edition of the game it comes with a life-sized model of the Tostador flamethrower.

- Hearthstone has the Improvised Flamethrower card for the Tavern Brawl game mode.
- Thanks to the very unique weapons system of Homefront: The Revolution. A homebrew flamethrower is one of the available weapons on hand, but the player must first purchase the crossbow.

It's gas is carried in a medium-sized horizontal green jerry can with the nozzle/barrel being a whole emptied fire extinguisher.
- In Horizon Zero Dawn's Frozen Wilds expansion, the Forgefire is a flamethrower made out of what seems to be part of a Bellowback's blaze pouch, with some wooden bits for handling and aiming.

The current trope image from Team Fortress 2 is also available as a Meat Fortress weapon.

Suggesting that it may have been made by a student or a survivor that used to reside there.

- Metro has the various flamethrowers made from cobbled together spare parts. In the original Metro 2033, it's a fixed weapon, but from Redux and Metro: Last Light onwards, it can be carried around, using its own unique ammo in the form of fuel oil that has to be scavenged. They're especially effective against mutants dwelling on both the surface or in the Metro's tunnels and are still lethal against human enemies, where they thankfully don't explode from stray bullets.
- In the second ObsCure game, there was to be homebrew flamethrower which seemed to have been made with a water gun (presumably loaded with gasoline or some other flammable liquid) with a wick placed in front of the barrel. Obviously the ignition of the wick would have ignited the flammable liquid fired to obtain a jet of flame, but the weapon itself was cut from the game for unknown reasons. However, it does make an appearance in Final Exam but it appears as a somewhat regular flamethrower.
- In Oddworld Soulstorm, you can make a flamethrower using the tank of a fire extinguisher, a battery, a wiring kit, a steel hose and Soulstorm Brew (a drink whose flammability is its least lethal quality). It's far more wild than the officially produced ones the guards use.
- Team Fortress 2's Pyro primary arsenal is mostly made up of homemade and jury-rigged flamethrowers for them to use. Which probably makes sense as the Pyro themselves are definitely not someone would ever willingly give a flamethrower...or anything of remotely-lethal capability. For example, the stock flamethrower is made out of a long metal pole, connected by a hose to a propane tank. The tank is attached to the pole via fastening bands. A continually lit pilot light can be seen at the nozzle. The trigger is made out of a team-colored gas pump handle. Also another thing to note is that most of the flamethrowers have an alternate fire called compression or air blast, which is a blast of cone-shaped gas emitting from the end of the weapon.
- In Resident Evil 7: Biohazard, Ethan can get a small homemade flamethrower named the "Burner", which is created by combining its two separate parts, the Burner Grip and Nozzle respectively. Also its fuel/ammo can be created by combining Solid Fuel and Chem Fluid together. It's most effective when taking on Marguerette and her insects, which coincidentally when you get to her part of the Baker Estate, where you acquire the parts to make the Burner anyways.
- One of the weapons in the first The Suffering game, is a homemade flamethrower that needs to be assembled from different parts like a bicycle pump, gas cans, and flares. You can find the instructions that tell you what you'll need, although they are not necessary for creating one. Judging by the instructions and how it was seen next to the corpse of a prisoner, it seems it was going to be used for rioting or escaping the prison.
- In one Skullkickers side story there's a whole band that embody the Instrument of Murder trope. One member having axe blades on their lute lute, a hidden sword inside of a flute, a harp that doubles as a bow, and lastly a hurdy gurdy that's also a flamethrower.
