If you ask a person to draw a bomb, this is probably what you will get: a spherical black object about the size of a bowling ball with a fuse sticking out of it. Sometimes it may have the word "Bomb" (or "Boom") written on it in bold letters. Very common in cartoons and comic books, and somewhat surprisingly in the relatively new medium of video games.
This actually has a basis in history: before the mid-19th century, contact or proximity fuses for detonating explosive payloads had yet to be developed. The only means by which an explosive shell or bomb could be feasibly detonated from a distance was by a slow-burning match cord. In Western militaries, these weapons often took the shape of an iron sphere with a match cord sticking out of one end, and the Cartoon Bomb actually is a realistic representation of such ammunition. The resemblance to cannonballs is not coincidence; they were often designed to be fired out of cannons, or rather carronades, mortars or howitzers. (The "bombs bursting in air" from the traditional US song "The Star-Spangled Banner" were of this variety.) A skilled bombardier could estimate how long it would take for the bomb to fly to the assumed target and cut the fuse to appropriate length so that the bomb would explode exactly at the desired moment.
Early hand grenades also took this shape, as did mortar bombs. In fact, the "pineapple" grenades used by Soviet, Franco-British Commonwealth, American, etc soldiers during World War II were variations on this type of bomb. There were only three major differences. They included a built-in fuse lighter for convenience. (That's the handle-and-pin assembly made famous by the Pin-Pulling Teeth trope.) They were oblong, and they had grooved skin so that they would fragment more easily and disperse shrapnel. (That's why they're called "frag" grenades.)
As Cartoon Bombs generally tend to appear in cartoons and comics, they usually tend to not do any serious damage — at least to characters. They may cause damage to their inanimate surroundings, but usually, the worst a victim within the blast range suffers is Clothing Damage and Ash Face, both of which are usually healed by the next scene. As a result, when a Cartoon Bomb is seen in a work, it tends to be more of a slapstick prop as opposed to a deadly weapon. Despite these bombs being very old-fashioned, they're prominently used in many video games, since the black-ball with sparky fuse is very iconic and quickly recognized by players.
This is a subtrope of Incredibly Obvious Bomb, but that also includes more realistic but still blatantly obvious bombs like the classic digital timer (often ticking to make it even more incredibly obvious) attached to a bundle of explosives (which is fairly common in cartoons). Compare Plunger Detonator, which is the standard cartoon way of setting off explosives from a distance. Often thrown by Bomb-Throwing Anarchists.

- Reflecting its real-life origins, a stylized cartoon bomb appears in insignia of several real-life ethnic-Europeans' military units, including several elite ones.

Now, why is this a subversion?. Because they weren't made of metal, but rather they were made◊ from clay, if they were made of metal they wouldn't be able to explode, the only metal part is the caltrops that were contained in the bomb. Here, take a look.◊ these were used until The American Civil War.
- One of these maimed Harold Lloyd early in his career. When on a photoshoot, he was handed one to hold. Thinking it was an inert prop, he jokingly lit it with his cigarette. It wasn't. In the end, he lost a couple of fingers on his right hand, was temporarily blinded and suffered some lacerations to his face. note He was well and truly lucky that that was the extent of his injuries. Whenever something looks like an explosive, treat it as such -- you may not be as lucky as Lloyd.
