The opposite of a sausage fest or testical festival. A party consisting of 90% or more females. A woman's vagina looks like a roast beef sandwich, hence a large gathering of vagina = the largest Arby's roast beef sandwich the BIG MONTANA.

Get the Big Montanamug. A sloppy, unattractive,unmanicured vagina. Maybe some Arby's or Horsey sauce could make it more appealing.
Hey, what are you having for lunch?
The Arby's Big Montana!
Damn, that snatch looks just like the Big Montana from Arby's.
