look up any word, like plopping:
a person with an extremely large torso but with severely short legs. They also have a face of a bird, namely an ostrich and the legs resemble the ones of a pig. They are also really stupid and have the intelligence of a blueberry.
Look at that chick. Her legs are so fucking short and she kinda looks like a bird, what a Postrich.

Something so cool and luxurious that even the ordinary rich can't afford. You have to be WAY-WAY-rich to have it.
Yo Papi, your 3D printed ear bling is so postrich.
