A friend of Sweetie competes in Roller Derby. For the uninitiated, Roller Derby is a women-only sport where the aim is for a single skater (the "Jammer") to lap the opposition (to score points) without being knocked of the track (to avoid injuries). Each skater has an alias, such as "Abrasion Hussy", "Hildabeast", "Scoli O'Sys", and "Octavius Seize-Her", and there is much throwing of elbows and crashing to the floor (or into the stands).
Truth be told, it's quite entertaining! It doesn't need much of an attention span, doesn't last too long, and it's just plain wacky! What more could you want?
