Yeet Cannon, is a common term for describing a large bore firearm with little in the way of a practical function or common use (I.E. concealed carry or hunting), other than to be amusing and/or enjoyable to use. However this definition can also be applied to a firearm of a smaller caliber as long as the firearm is somewhat impractical to use and/or accessorized in a excessive and/or ridiculous manner (I.E. An AR pistol with a drum magazine and a ballsack foregrip).

Though sometimes used to refer to any gun, the original reason for the term "yeet cannon" was the idea of throwing the gun itself (that is to say, yeeting it). As a result, most "yeet cannons" are unreliable guns, the sort that would be prone to failure and require that it be physically thrown (yeeted) at a threat in a last-ditch effort.
This term can then be broadened to any sort of failure-prone firearms situation, such as a cheap mag or rounds. Either of these would also lead to a possible operation error that would require a quick-thinking firearm enthusiast yeet their chosen missile launcher at someone (or something).

While the Hi-Point pistol with the official name "Yeet Cannon" is an enjoyable meme, an example of a real manufacturer that might frequently be accused of producing "yeet cannons" would be Taurus, whose pistols have a reputation for failure (at the time of this writing, Taurus has released a few pistols suggested to be higher-quality than previous models, so in the future they may be clean of this association). Another example of a "Yeet Cannon" would be a disposable improvised firearm, also known as a zipgun (heavily illegal to create pretty much anywhere). The "four winds shotgun" made out of a simple metal tube and a cap/nail would be an example of an improvised yeet cannon.

In any case, despite this origin, you are quite liable to hear any ol' weapon referred to as a yeet cannon, right up to a Vulkan cannon.

A Yeet Cannon in contemporary parlance refers to a pistol or other firearm used in an aggressive manner.

The Spartans used yeet as a battle cry when fighting the Persians at Thermopylae, as translated from neocontemporary Persian accounts of the battle. It is unknown if the term was in common use in the Greek city-states prior to the battle or if it was coined during that engagement.

The Massachusetts army holding Bunker Hill and Breed's Hill yeeted at the British regulars and at least one historian asserts that Major General John Stark, King in the North, yeeted in the general direction of General Howe during the British attack on his position. Though cannon were present during that battle, yeeting was only commonly employed by infantrymen of that time, particularly during bayonet charges.

In 1831, Mexican authorities gave a cannon to the settlers of Gonzales to protect themselves from Comanche raids. In 1835 Colonel Domingo de Ugartechea, the Mexican commander in Texas, requested the return of the cannon. They responded with a single word, YEET! The famous Yeet Cannon would be emblazoned on what would become known as the Gonzales Flag, the forerunner of the eventual Texas State Flag.
