What is a 'pigtail' in the context of rodeo?

In the context of rodeo, a 'pigtail' refers to a string that is attached to the barrier, which is an essential component in the timed event competitions. When a rider is ready to start their run, the pigtail is pulled, releasing the barrier for the animal to run out, thereby starting the competition. This setup ensures that the rider has a fair start and is critical for timing purposes, as it helps maintain a consistent and fair starting point for all competitors.

The other options do not accurately represent the term 'pigtail' within rodeo. A specific type of horse, a technique for catching animals, or a nickname for a rodeo clown do not convey the importance or functionality of the pigtail in the context of a rodeo event, highlighting the role of the barrier in competitive settings.
