Category:WTH?

What is the WTH? category?
The WTH? category is for things that make you question why it exists so all the items like diet water for example go here. Even if it is proven to be a thing that doesn't exist it can still be put here if the following criteria have been met:
 * 1) It tricks someone
 * 2) Someone unironically wants it
 * 3) It altered name of an existing thing that makes it have no sense. E.g. The Meatless Meatball.

Not all criteria must be met only one.
