"Ventripotent" is a fun adjective for subtle insults, as it means having a large belly, or gluttonous in eating. It came to English through French from the Latin roots "ventri" (belly, stomach) and "potent" (powerful). It's not a very common word in English, but some well-known authors have used it:
"The ventripotent mulatto, the great eater, worker, earner and waster, the man of much and witty laughter, the man of the great heart and alas! of the doubtful honesty, is a figure not yet clearly set before the world..."
-- Robert Louis Stevenson, Memories and Portraits
"I hope.. that the Monico made up.. for the absence of
one ventripotent scortatory Krut."
-- Dylan Thomas, 1942 Letter
Google searching reveals that the word is used far more often in French than English, though the meaning is the same -- for example, a review of Shrek 2 describes the title character as "ogre vert cradingue et ventripotent" (a grubby, big-bellied green ogre").
