What is "excelebration"

Excelebration (foaled 13 April 2008) is an Irish-bred Thoroughbred racehorse. As a three-year-old he recorded wins in the Mehl-Mülhens-Rennen and Hungerford Stakes, before winning his first Group 1 in the Prix du Moulin de Longchamp. After finishing second to the unbeaten Frankel in his first two starts of 2012 he recorded successive victories in the Prix Jacques Le Marois and Queen Elizabeth II Stakes. These were followed by a fourth-place finish in the Breeders' Cup Mile, after which he was retired to stud. He was trained by Marco Botti until being transferred to Aidan O'Brien at the end of the 2011 flat season.
