A competitive sport in the gay community where men will raise their own gerbil at home and bring it to parties to compete against other mens pet gerbils. To be a gerbil racer, one must show their gerbil is far superior with its penetration into the owners anus, thus winning the race.
Hey Kye, I know your the Gerbil Racer Champion, but can you show me how you get the maximum penetration to take the gold metal?
