So I have this book by Arthur Quinn, "Figures of Speech." It's a veritable treasure-trove of rhetorical terms with examples and pithy commentary.

Here is a sample:
"On the night of June 21, 1932, Joe Jacobs, a professional prize fight manager, after hearing that his man had not been awarded the decision, achieved for himself linguistic immortality by shouting into the ring announcer's microphone, 'We was robbed!'

'We' does not ordinarily go with 'was.' And we might think that Jacobs had simply made a grammatical mistake of a rather rudimentary kind. Yet, if he had said 'were,' he likely would have been consigned to the same oblivion as was the smug winning manager. Far from being a mistake, 'was' was an inspiration. It was, to be more precise, an ENALLAGE, which is just the rhetorical name for an effective grammatical mistake."

The book goes on to discuss several dozen other rhetorical figures, all in amusing detail and with copious examples.

For example, combine ENALLAGE with another widely-used figure, METAPLASMUS, or the deliberate misspelling of words, and you have teh internets, in a notshall.
