Rachel and I think a great idea for a party full of raucous laughter and dancing with fire would be St Elmo's day, which appears to be June 2nd.
I'm imagining potluck, music, 80s movie references, and of course spinning. Alas the lack of location.
EDIT: For the unChurched, St. Elmo's the patron saint of sailors and is known for fire that doesn't burn. See also,
