"Dirtbike" refers to the penis of a male who has an unhealthy penchant for anal sex with his female partner. The name stems from the man's desire to ride the female's 'Dirt-Track'. Dirtbikes may also come equipped with "mud-tires" if the female is experiancing diarrhea at the time of intercourse, and "snow-tires" which refers to the male riding the 'dirt-track' after he has previously climaxed in it.
