IMO talking while your opponent is shooting, unless they are in the conversation with you, is nothing but a shark move.

Sometimes, it's pure ignorance, not a shark move. BUT, I do believe that it's okay to talk UNTIL someone with a cue bends over to make a shot, as long as it's okay with both parties. I'll joke a little with my opponent, but I'm usually pretty serious about league or tournament games. If I'm just playing pool, I've probably got my mouth open.
