This word originally was used in Mad Max Beyond Thunderdome (1985) to describe a place in which losers fight to the death, but now used to describe:

1. A place at the center of potential conflict, usually political or controversial conflict
2. A place in which anything goes, in contrast to outside the thunderdome where rules do not apply

The greatest way to settle a dispute in the world. It has been popularized by many Ivy League fraternities to settle any moments of conflict. As two people dispute, they will challenge each other to "a thunderdome". This occurs when a spectator takes a trash can(places it in between the contestants to be throw up into), fills as many solo cups as possible with beer, and plays the song "final countdown on repeat". The goal is to settle the dispute by drinking as many as the beers in the solo cups as you can until you throw up. The first person to throws up loses, and foam does not count.

Also known as Chunderdome, Thunderdome is a one-on-one drinking duel where each person attempts to drink a beer a minute until their opponent either taps out or vomits. Thunderdome-ing is an aggressive yet effective way to settle a dispute or challenge someone's honor. The challenge also must be accompanied by the playing of AC/DC's "Thunderstruck" on repeat until the challenge is completed.

Threatening to take someone "to the dome," i.e. to the point of uncontrollable vomiting, should not be done lightly, as the few brave souls who have gone to the dome can tell you. It is common etiquette for the victor of the Thunderdome to finish by taking themselves to the dome as a sign of respect to their opponent and to the challenge itself.
"I'm taking your ass to the dome!"

Guy 1: "Wednesday is sandwich day and that is final!"
Guy 2: "Too bad, I hate sandwich day."
Guy 1: "I'll Thunderdome you for it!"
Guy 2: "Challenge accepted!"

Where the most intense roller hockey games on the planet take place. Where its water bottle hunting season for 5 months straight. And all the cheerleaders are 300 + lbs and all wear skimpy outfits. Where the great Javi-bhulin once played goalie and his mylec pads still swing from the rafters till this day. Some say the Niles , Thunderdome Arena is responsible for global warming.
I'm going water bottle hunting at the Thunderdome today

Its time to "Dome" it up

We fear change!
