Fat-buttocked

Gluttony, rotund and fat-buttocked, was upturned into a barrel of excrement; Anger, face contorted with rage and agony, had his skull prised open and his brains sucked out by hunchbacked devils.

Indeed, he transforms his superior into the very personification of gluttony: “... he was fat, oily, refined, rotund, heavy, ponderous, weighty, massive, cyclopean, a giant in body, broad-chested, deep-bellied, fat-buttocked, his eyes set wide apart, with a jutting forehead, a ferocious countenance, commanding of respect, with a good shock of hair and a bull-neck.”
