The passageway behind/underneath the seats in an amphitheater, which allow patrons to enter and exit quickly and efficiently. So called because the people coming out of the openings looked as though they were being vomited out.
I'm heading out to the vomitorium to go to the bathroom and get a new beer before the next inning.
Vomiking is the act of vomiting out of your nose instead of your mouth. While this is not a true medical distinction, it is funny and should be.
A woman came into the emergency room because she was sick. When the doctor asked the reason for her visit, she replied that she had been "vomiking". The doctor corrected her and said that she had been vomiting, but she replied No, she had been "vomiking". He paused for a moment, not sure what to say next, because the woman was obviously sure this meant something else. He decided to ask her to explain the distinction, to which she replied "vomiting is when the food comes back out your mouth, vomiking is when it comes back out your nose."
