boñiga

Etymology
Highly disputed; officially, the Royal Spanish Academy does not recognize any etymology. However, some etymologists have theorized that it may have originated either from Vulgar Latin *bovinica ("pertaining to bovines") or from.

Some have also theorized that it may come from, from *moñigo, from *munnigo. from, whence originates.

It is also theorized that it may have come from or possibly from  (both of which are highly improbable given that neither of them have any sort of resemblance to cow or horse dung).

Noun

 * 1) cow or horse dung
