Reggie Corrigan, writing in The Times, has no time for glory-supporting "Lunsters".
"I’ll never forget the hype and the mania and the scramble for tickets before the Leinster v Munster semi-final in Lansdowne Road three years ago. There was talk back then that if only the GAA would open up Croke Park, we’d have had no trouble filling it. Well three years on, and it’s actually happened – and there still aren’t enough tickets.
"I’ve been scrounging around same as everybody else. It’s a pain, but it’s also wonderful. The rivalry between two great teams and two fantastic sets of supporters is at the heart of what has made Irish rugby great.
"There’s just one problem. Munster’s fantastic success in the past few years has spawned a mutant breed of rugby fan – the Lunsters. They are born, bred, living and working in Leinster but they have turned their back on their own province and decided to support the men in red.
"I can hear already hear their yelps of self-justification: Everyone is entitled to support the team of their choice. Yes, but only within reason. Of all the arguments I’ve had with these people over the years – and I’ve had plenty, believe me - I’ve never been convinced."
