Yeah its not a typo, the sport’s name is Bossaball (my mac is underlying it with a red line as i type 😛 I guess it is a typo afterall). I never heard of it but going by the video it looks like a really fun sport.
“Bossaball is a sport invented in Belgium. It is similar to volleyball, but also includes elements of football (soccer), gymnastics and capoeira. Each side of the court has an integrated trampoline, allowing players to bounce high enough to spike the ball, and a number of inflatable barriers.
Bossaball clubs exist in various countries including Brazil, Germany, Netherlands, Spain, Portugal, Romania, Singapore, Kuwait and Ecuador.”
