Cow-orker
A cow-orker is a person who specializes, either professionally or as a hobby, in orking cows.
Cow orking dates back to the Middle Ages (100 A.D. - 1953 A.D.), and the first cow-orker, St. Francis of Assisi. Over the years, various non-holy methods of orking cows have been developed, as ranchers with large herds needed a quick and easy way to bring their feisty cows under control.
Cow Tipping
Cow tipping, while unrelated to cow-orking, remains a highly competitive sport in several states. The sport remains small, primarily due to the difficulties in gathering a paying audience.
Bull-orker
The National Cattle Producers Association has an ongoing campaign to warn people of the negative consequences of attempting to ork anything but cows. Several deaths have resulted in untrained individuals attempting to ork bulls, llamas, sheep, rugs, mice, and carburettors.
Cow-orking in Peter Chimaera's work
In Peter Chimaera's Quarter-Life: Halfway to Destruction, there is a character known as Cow-orker Jim. Not much is revealed about Jim's life, and it is uncertain whether Cow-orker actually refers to someone who orks cows, or just a poor spelling of Co-worker.
