Hoop is a mature kid
No, sorry but I'm going to have to nip this is the bud right now. There is no way this kid is going to be called Hoop. NO WAY. I can live with Hoopy (Alt: Hoopie). Also acceptable would be The Hoopster or the Hoopmeister General. If he starts dribble the ball off his feet you can call him Ooops or Oopsie. But Hoop is right out. Don't make me warn you again.
ANFSCD:
Mr Anemone: Oh, I don't suppose we know what an 'oop is. I suppose pater thought they were a bit common, except on the bleedin' croquet lawn.
Mr Chigger: Oh, a hoop.
Mr Anemone: 'Oh an hoop.' Thank you, your bleeding Highness. Now. Look.
Mr Chigger: Go on, right the way along.
Mr Anemone: All right, all right, all right. Now, where's the bleeding wire, then?
Mr Chigger: That hoop's got a hole in.
Mr Anemone: Oh Eton and Madgalene. The hoop has an hole in. Of course it's got a hole in, it wouldn't be a hoop otherwise, would it, mush!
Mr Chigger: No, there's a gap in the middle, there.
Mr Anemone: Oh, a gahp. A gahp in one's hhhhhoop. Pardon me, but I'm off to play the grand piano.
