When an owner registers their horse to complete in major races, they need to satisfy a bunch of requirements. Some of which: the name can’t be the same as another horse, it can’t use a copyrighted term, there is a length limit, the name can’t be the same as a real person’s name, and it can’t be profane. Also, a lot of people choose names because they think those specific names will bring them luck or just because they are fun. Sometimes, people also try to include names in the horse’s name that are related to its lineage
