See, do we have to call it Mungoball? It's disrespectful to disabled people for a start, and I mean by that it's wrong to use a term that is a very disrespectful to mentally disabled people and then apply it as a nickname for a sport. And it just sounds like the user is some snobbish and superior acting. I know a lot of League supporters rubbish rugby and denigrate its fans, but Mungoball is a bit on the nose as a term.
(and I know I used it once when I first heard the term, but on reflection, it's not really appropriate)
