Yes, I really dislike it also. Totally get it was meant as a parody of how we're referred to in the media but Rooney's name & 'brand' is now so toxic with some, its becoming divisive.
A vote as @ck- suggests would maybe be the fairest way of deciding whether to keep it or not.
In the thread 'Rooney In', @Highgate argued one of the reasons we should dispense with Rooney's services is:
"Sacking him will mean we won't have to look at the 'Wayne Rooney's DCFC fans' anymore."
To the mods.... Help us reclaim our club. Even if we must have a celebrity in the managerial hot seat, and it seems we must, then at least let this forum lead the way in showing the world that the club is bigger than any individual.
Derby County Football Club.
Then we can say things like "DCFC's manager Wayne Rooney..... needs to get wins".
