When two or more people are contesting something they need to fight it out. Like in the old movie with Mel Gibson.
Two guys are fighting over the last slice of Pizza their buddy says, "You guys need to Thunderdome It, Fight it out with rusty spoons or somthing. Two men enter, one man leaves, Winner gets the Slice."
