I've namechanged for this as I rant about it constantly in real life. My maiden name is unusual and spelled somewhat similarly to Borat (but is very much NOT Borat and isn't pronounced as Borat. You could not possibly think the name was Borat with even the most basic grasp of phonics).
Before Borat became a thing, literally nobody had a problem pronouncing my name when they saw it written down. As soon as it did, whenever I was called by the bank/doctor's surgery/etc etc, they'd address me as Ms. Borat. People would see my name written down and chuckle and start saying 'Very Nice!' etc etc. Even now, anyone who hasn't heard me say the name automatically pronounces it as Borat. I've even, on the odd occasion, had letters addressed to me as bloody Ms Borat.
My mother was baffled by the whole thing as she had the same experience but didn't know who on earth Borat was or why, all of a sudden, people were having a chuckle over her surname.
I'm very fond of my maiden name apart from the ridiculous Borat connection and, having changed it when I got married to avoid the Borat annoyance, I've since gone back to it. But fucking hell, it annoys me intensely. I don't believe anyone sees my name written down and genuinely thinks it says Borat- I think they want^^ my name to be Borat because it gives them amusement. Thank god nobody can seem to remember the Borat catchphrases any more or I think I'd lose it.
Bloody fucking Borat.
I feel better for getting that off my chest, thanks OP!
