I assure you, as a professional educator, than mispronunciations of "hyperbole" are not a phenomenon strictly found within one sex.
I can pronounce it just fine, and I don't even
watch American football.
My claim was not that all people mispronounce the word, only that both men and women occasionally do; or to put it another way, that vaginas do not, in my experience, meaningfully prevent hyperbolic mispronunciation. As to whether or not
you personally mispronounce the word in question, I would be quite surprised if our two great nations shared any clear common conviction as to its "correct" pronunciation to begin with. It has a few too many vowels for that to be hoped for.
Even in Greek, you're spoiling for a fight between modernists, Erasmisns and reconstructionist every time you hit an eta (the "y"). In rich kid grammar school, that's an "ey" sound. In modern Greek, an "ee". And historians debate between "ey" and "eh". So the original Greek pronunciation may well have been something like "Hepper Bow Lay". Which is all but unrelated to any "correct" English permutation.
