In the asturleones language of Aliste, testicle. As I child, the alistanos capaban the pigs in the pen, i.e. cut them riles, disinfecting the wound with piedralipe bluish-green color. They were then cleaned you riles them, they are frying, and they ate. Perhaps it was thought that this increased fertility, at least I could deduce by the pleasure and joy that ate. But this was not talk.
