Kim, you are very bad!
I've seen it before. I think it's a genuine eggcorn, rather than a spelling error.*tapity-tap*https://languagelog.ldc.upenn.edu/nll/?p=2550
All in one document. A spelling checker is not a magic instrument but it would have caught all of those in a minute. Why the fuck didn't you use one?
An eggcorn is the alteration of a phrase through the mishearing or reinterpretation of one or more of its elements, creating a new phrase having a different meaning from the original but which still makes sense and is plausible when used in the same context.
