Aristocrats are very easy to identify - the men look like inbred halfwits and the women look like horses.
Hated by everyone, even only slightly less posh people.
They are the target of the famous "The Aristocrats" joke told by many stand-up comedians.
So the term can be used for people supposed to have pervert sex with their family members and family animals in the most disgusting ways one can imagine.
The Magalonas, The Yulos, The Ayalas, and The Zobels are notable descendant families of Filipino aristocrats.
