Wikipedia definition
2. CacographyCacography is deliberate comic misspelling, a type of humour similar to malapropism. The term in the sense of "poor spelling, accentuation, and punctuation" is a semantic antonym to orthography, and in the sense of "poor handwriting" it is an etymological antonym to the word calligraphy: cacography is from Greek κακός (kakos "bad") + γραφή (graphe "writing"). A common usage of cacography was to caricature illiterate speakers.
