To answer the last question, Luffy calls Law Tora-o, which comes from his name "Torafaruga". That sometimes gets translated as "Torao" or "Tra-guy" or "Tora-man". Probably Chopper and Co use the same nickname Luffy uses for Law in this case.

About the attacks, I think that CoA+Gear 2nd or gear 3rd attacks have "animal+weapon" themed names. Think of it like Zoro's attacks who have a food theme pun.

I'm tired of Chinjao. Please, no more.
