'Lonnacht' is the portmanteau word that rugby has been waiting for since Munster turned to shite about four years ago and the 'Lunsters' receded into history.
What makes the 'Lonnachts' a potentially more formidable force is the fact that they are in many cases joined by the 'Monnachts'. But they might now also have a famous Leinster face on their side.
Former Leinster and Ireland centre Gordon D'Arcy's Irish Times column has proved ever-popular since its inception ahead of the Rugby World Cup last year, with the 36-year-old's then-controversial take on former England centre Sam Burgess having since been proved spot on.
Today, however, saw D'Arcy dip his toes in a wholly different controversy, as he unashamedly - and perhaps even bravely - crossed the line right into 'Lonnacht' territory, with a particular fondness for Matt Healy shining through his Leinster blue.

But before any Leinster fans ostracise the 82-time international from Wexford, it's worth noting that his father is from Ballina. He might not have mentioned that.
In fairness to D'Arcy, he did also retweet Brian O'Driscoll's 'COYBIB' war-cry before kick-off. And there can't have been too many Irish rugby fans who would have begrudged Connacht their monumental success today, you know, bar the thousands upon thousands of bitterly disappointed Leinster fans who watched their side's limp display against the new champions.
