big montana

A donkey punch-tobogan, followed by a combination Cleveland steamer/Dutch oven.

"No way! An actual Big Montana?"
"You bet your ass dude! It was everything I've ever dreamed of!"

Arby's Big Montana

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.
