Angie, Carlin, I know you're in shock and I'm sorry, I truly am. But it's something we're going to have to face together because, according to Urban Dictionary (which everyone knows is the elite resource for checking stuff):
"[Ingenuine is] not yet an actual word. Incorrectly used when trying to describe something that is the opposite of 'genuine.' Usually confused with "ingenuous", which means "gullible", and "ingenuity" which means "inventive originality".
Despite it being a completely made-up term, Jamie used it no fewer than six times in the space of about three minutes in the latest episode of the reality TV series; so many times, in fact, that I have to wonder if he's trying to make 'ingenuine' happen.
If that's the case, please – stop.
Urban Dictionary suggests using the word 'disingenuous' when you're going for the opposite of 'genuine. But why not just stick to the classics and call someone fake?
To be fair, Jamie did use that term, too, while he was ripping into Carlin Sterritt during the cocktail party to end all cocktail parties.
