Hooverball! https://en.m.wikipedia.org/wiki/Hooverball
It’s a lot of fun to play! super egg behavior from like 20 years ago before I knew; I was in the US Hoover-ball National championship games and while my own male team didn’t win the women’s team that did win was down a lady and when they asked if a male would play with them I was super delighted to and confused why I was the only volunteer!? I was the worst one on both the teams I played with but they were super nice anyway.
So I’m a legit hoover-ball national champ! But only by dumb luck.
