Like basketball but no dribbling with ball. More static and throwing to your team mates. It's a "girls" game. We weren't allowed to play basketball like the boys were in school :-/
We would occasionally play with the girls in junior school. Harder than basketball, in a lot of respects. No backboard, for a start!
It's pretty common for girls to play it in School here in the UK (at least I think it is). It kind of like basket ball I guess.
