What would you use a crupper for?
Correct answer: Horse back riding

I am not a number.
Why is it called "horse back" riding? Isn't the "back" implied? Can you do "horse front" or "horse side" riding? These are the important questions. Ha ha ha.

Stinky, it's the solid part of the tail, the very end of the spine.

A Crupper probably more commonly seen in Trotting horses where it is part of the harness placed under the top of the horses tail that assists in firmly attaching the cart or 'sulky' that the horse pulls in a race. I believe 'horseBACK' riding is only an American term, we 'downunder' in NZ & Aus like most places are aware you ride on the horses back, even if riding side saddle!
