What is this? No fair checking comments before you guess!
UPDATE: The winner is Nerd Rage, who guessed that it was a goat tail. Indeed it is. When I was at the Orange County Fair a few weeks ago, I was quite taken with the cropped tails in the goat pavilion. It appears to be the finishing touch on a prize goat, and there were several different varieties on view. However, this one was the most common.
