A human female distinctly different from their relatives the Cow and Horse, a Buffarillo is distinctive in it's androgen enhanced upper body and slim to non-existent lower body. Often the lower body is large but in no case larger than the upper. Ugly is always a Buffarillo trademark.
Normally, Buffarillos graze alone or with Cows and Horses. However, it is not a total oddity to see 2 or 3 together.
The Herd at the next table had 2 Horses, 2 Cows and a Buffarillo.
