Huh. The image was very weird to me, but I’ve played some version of this as a kid. Team one makes this structure against a wall, team two send people to jump and crawl forward, the goal being to break the “bridge”. I can’t even remember what we fucking called this game, this was in Lebanon in the late aughts/early tens.

There’s something about how most teenage boys are wired that made it feel exceptionally badass when your team was on the bottom and you didn’t crumple when it was the turn of one of the large gentlemen on the other team to jump.
