A ‘Robin Hood’ is a coveted but expensive trophy for any archer. This is where one arrow strikes the back of another arrow already embedded in the target. This tends to happen indoors where the targets are much closer to the archer. It is expensive because the first arrow is destroyed (obviously!), but the incoming second arrow is also damaged and unsafe to use. At up to £25 an arrow, it is a unique and expensive sound!
In fact, the incoming arrow still scores along with the wrecked arrow!
