A room, usually only in a well-to-do Ancient Roman house, where one went to vomit
between courses. In Ancient Rome it was fashionable
to eat gluttonous amounts
of food. The ultimate expression of this, usually by the upper crust, was to eat a meal so huge
that one could not physically
finish it unless one took breaks to vomit
The vomitorium was the product of the accepted practice of bulemia.
