My mother (English teacher and grammarian extraordinaire, rest her soul) abhorred any kind of misspelling. No big surprise, I don't mind it at all. Phonetic transcription is a skill linguists practice for years. A creatively spelled word here and there slows your reader down, gets meaning across in a way a correctly spelled word can't.
Hey, mind your own business. (Direct, a little hostile.)
Hey, mind your own biznazz. (Direct, but funny. Am I right?)
Posting this picture because it's how I feel on the brink of another birthday. Creative. Somewhat fractured. Sparkling.
