Cowboy polo is a variation of polo played mostly in the western United States. Like regular polo, it is played in chukkars (periods) with two teams on horses who use mallets to hit a ball through a goal. It differs from traditional polo in that five riders make up a team instead of four, western saddles and equipment are used, and the playing field is usually a simple rodeo arena or other enclosed dirt area, indoors or out. Also, instead of the small ball used in traditional polo, the players use a large red rubber medicine ball and use mallets with long fiberglass shafts and hard rubber heads.

The horse breed most often used for cowboy polo is the American Quarter Horse, due to its agility. Unlike regular polo, where multiple horses are used within a single game, riders do not change horses between chukkars, but instead are only allowed two horses, and in some competitions are required to ride one horse throughout. This ability to compete with relatively few animals has given the sport its nickname, the "average man's" sport. Horses competing in cowboy polo are often older, experienced animals with steady dispositions who have come to understand the basic purpose of the game and can assist their riders.

Ralph Lauren (born Ralph Lifshitz, October 14, 1939) is an American fashion designer and business executive; best known for his Polo Ralph Lauren clothing brand.

Ralph Lauren was born Ralph Lifshitz in the Bronx, New York, to Ashkenazi Jewish immigrants, from Pinsk, Belarus: Fraydl (née Kotlar) and Frank Lifshitz, a house painter.

Ralph attended the Salanter Academy Jewish Day School followed by MTA (now known as the Marsha Stern Talmudical Academy), before eventually graduating from DeWitt Clinton High School in 1957. In MTA Lauren was known by his classmates for selling ties to his fellow students. In a moment of spontaneity, when asked what he wanted to do in his Clinton yearbook he stated under his picture that he wanted to be a millionaire. During the summer, Ralph attended Camp Roosevelt (Monticello).

At the age of 16, Ralph's brother Jerry (who was his guardian) changed their last name to Lauren to avoid the unfortunate obscenity reference Lifshitz has in English (although Ralph's brother Lenny retained the name). Apparently Ralph was teased about it in school. “My given name has the word shit in it,” he told Oprah Winfrey. “When I was a kid, the other kids would make a lot of fun of me. It was a tough name. That's why I decided to change it. Then people said, "Did you change your name because you don't want to be Jewish?" I said, "Absolutely not. That's not what it's about. My cousins who lived in California had changed their last name to Lawrence. So I just thought, "I'm going to pick a nice last name"—it wasn't particularly connected to anything or anyone."
