Comatish
Theoretically, Comatish could be considered a language, although students of linguistics argue whether it is really a language, a dialect or just a massive joke. It seems at times to be nothing more than a collection of the most common mistakes made by people first learning Esperanto. It includes such oddities as words used in place of their homophones' synonyms and vice versa (such as "thatcraft" for what Esperanto speakers would call "witchcraft"), as well as occasional inclusion of confusing and conflicting grammatical rules and words from a hundred different languages.
