The tag of 'party poopers' won't affect the carnival atmosphere as thousands of Ulster Rugby fans journey towards Dublin today.
Not many people would relish the prospect of being the one to cut Brian O'Driscoll's career short – but that's exactly the aim of 6,000 travelling fans as they look to cheer Ulster into the final of the RaboDirect PRO12 final.
Home side Leinster are favourites having topped this year's group but Ulster will be out to make amends for defeat in the final of last year's competition.
Whatever the outcome, the atmosphere at tonight's semi-final in the RDS in Dublin promises to be electric – with Ulster hoping to stop a current three-year trend of Leinster ending their season.
Ulster Rugby spokesman Neil Briton said that Ulster fans will be doing everything in their power to cancel out Leinster's home advantage.
"The wonderful thing about Ulster is that no matter where we play our fans are right there with us and that's why they are deemed the best in Europe.
"I have no doubt that they will be bringing that atmosphere and passion to the RDS and giving the team the best possible chance to reach the final."
Chairman of the Ulster Rugby Supporters' Club, Iain Campbell, said: "I think everyone is quietly confident and certainly looking forward to such a great occasion.
"But I think we have a great chance."
