Back Roller

Back Roller
If I shot at the top of a loop on a roller coaster, you can hit me when you return?

Or how I can goal is to beat my friend sitting next to me? She is a kind of average.

This would require impeccable timing, the likes of which only the lead conductor Philharmonic New York could conjure. But go for it anyway – the worst case: you hit someone who had no intention of hitting, but still laugh at her ass.
