Climbing Games - Over the Line?

Been trying to remember where I saw this, maybe a climbing film/video somewhere.

it’s a campfire game where teams of 2 or maybe 3 compete to place a wine bottle the furthest they can beyond a line that you cannot step past. I recall seeing one person lean far across the line being cantilevered while another climbs on their body to reach really far. Different teams used different strategies. 

Any ideas on what this game is called? Where I saw people playing, etc. can’t for the life of me remember or dig up anything via googling random related word strings.

thanks!  

You ever play add on?

We just called it “Bottle Push”, but im sure it has many other names.

We used to throw a live 22 round in the campfire at Hueco Tanks and see when it went off. As I'm typing this I'm realizing how terrible of an idea that "game" that really was..

Aahhh the 80's
