name that river rafting game

What the heck is the name of that game river guides play at camp with two people, each standing on an ammo box (or 5 gal bucket) and are holding opposite ends of a throw bag, then try to pull each other off their respective boxes. The winner is the one still standing on their box.

I’d guess rope-a-dope.

don’t make me go to boatertalk, brah!
…uh, no thats not it…
