Eau Non Potable

Don't drink this guy's vomit, please. Interestingly enough, they call the cave-like hallways in the roman arenas vomitoires. This is not because people would often vomit during 'sporting' exhibitions held for show, but because they appeared to vomit up people into the arena. Isn't the word vomit a great word? It is so appropriately ugly and harsh.

VOMIT
c.1386, "act of expelling contents of the stomach through the mouth," from L. vomitare "to vomit often," frequentative of vomere "spew forth, discharge," from PIE base *wem- "to spit, vomit" (cf. Gk. emein "to vomit," emetikos "provoking sickness;" Skt. vamati "he vomits;" Avestan vam- "to spit;" Lith. vemiu "to vomit," O.N. væma "seasickness"). In ref. to the matter so ejected, it is attested from c.1390. The verb is recorded from 1422.
