my sister's birthday party, also vomitoriums

My little sister recently had a birthday party with a Harry Potter theme. I was not there, but I have been relayed information about it. In one of the games the guests played, they used spells from Harry Potter that have incantations derived from Latin. One of the ones used was "accio". It is a spell that summons an object to the user from across a room. In Latin, the word literally means "I summon". On an unrelated note, I found out that the Roman Vomitorium is not a room in which people are to vomit. It is just a door to the Colosseum that people spew out of when the games conclude.
