Mule

A mule was a hybrid animal produced by cross-breeding a male donkey with a female horse. Mules were typically sterile and were often used as a beast of burden by humans.

In the 18th century, Bartholomew Barebone, an American No-Maj, tipped off several American newspaper reporters about the existence of the wizarding world, showing them the wand Dorcus Twelvetrees Some of them printed pictures of Dorcus's wand, describing it as having a "kick like a mule" when waved.

Bane derisively asked Firenze if he was a "common mule" when he caught him letting Harry Potter ride on his back in 1991.
