Fanegas
A fatso or chunky person. Describes someone with a heavy, thick-set build, specifically with wide shoulders and a broad rear. It is often used to mock someone for being big-boned. (A fanega is an old unit of measurement for dry volume, roughly 55 liters, implying the person is high-volume or heavy).
You are such a fanegas, you are fatter than a pig. If they threw you in a tank of mercury you would sink, fanegas.
