It was supposed to be the argument of the decade if not the century -- the showdown between American Idol 2013 judges Nicki Minaj and Mariah Carey. If you watched last night’s show, however, you know that, thanks to FOX edits, there was nary more than a fizzle. Hrmph. Something else emerged, though, that was just as entertaining, and that was the start of the “NickiNames”. And it’s not a trend until it’s a Twitter trend, which it is (#nickinames).
