"Buzkashi or Kokpar is the Central Asian sport played among Kazakhs, Afghans, Uzbeks, Hazaras, Tajiks, Kyrgyz, Turkmens and Pashtuns. Buzkashi is often compared to polo. Both games are played between people on horseback, both involve propelling an object toward a goal, and both get fairly rough. However, polo is played with a ball, and buzkashi is played with a headless goat carcass" wikipedia.
