What is "petingo"

Petingo (1965–1976) was a British Thoroughbred racehorse and sire. In a racing career which lasted from June 1967 until August 1968 he ran nine times and won six races. In 1967 he was unbeaten in three starts including the Gimcrack Stakes and the Middle Park Stakes and was officially rated the best two-year-old in Britain. In the following year he was defeated by Sir Ivor in the 2000 Guineas but won the St. James's Palace Stakes and the Sussex Stakes. He was then retired to stud where he proved to be a very successful stallion before his death at the age of eleven.
