A riotous or drunken festivity
wine and party
A drunken orgy. Which is pretty much a useless word, because it is easily understood that an orgy has to have some form of alcohol to get from standing around doing nothing to suddenly having an orgy. However, if you want to sound intellectual using this will probably boost you up.
Derived from the Roman God Bacchus, the god of wine and sensual pleasures. Unfortunately Bacchus wasn't actually considered an Olympian, so he's not very well known and rarely pops up in many myths
Magistra: Today we'll be learning about derivatives!
Bambi: Yay!!! I've got a good one! Bacchanalia from the Roman god Bacchus. He's my favourite!
Nick: I wish I was a Roman... That way I could have bacchanalia's all the time.
