BBTag2.0 - Neopolitan Testing - Combos - Mash on b

Probably not optimal but it looks funny. I saw variants of these kinds of juggles elsewhere but they utilized J.A instead of J.B as the third rep which I THINK does less damage. J.B is a bit more finnicky though, the timing isn't too bad once you get used to it though.
