Barathrum [ba-ra-thrum; pron ba-rath'rum]
Latin, from Greek 'barathron'
An abyss; a bottomless pit; an insatiable person.
Recently my team at work went to dinner at an all-you-can-eat barbeque restaurant. Fransky, an incredibly tall and insatiable young man, went two or so rounds, I went three and most others went one to one-and-a-bit. The star of the night was clearly Toby, however, who went through a staggering six rounds, showed us all his stomach was barathrum and could never be filled.
