Vomitoria

Vomitorium in the Colosseum in Rome
(The roof has fallen in.)
People often think that a vomitorium must have something to do with barfing, and those stories about Romans eating too much and then making themselves barf so they could eat more. But a vomitorium is really much more boring than that.
A vomitorium is called that because it's a thing that something comes out of. In this case, it's a hallway in a Roman theater or an amphitheater that people come out of - the hallway that you walk through to get to your seat, or to get out of the amphitheater after the show.
