lol, quit worrying about the gestures :) They're just that, gestures. It is unknown (but assumed that) if they do nothing to NPCs. It's more of used for online stuff since you can't chat. You can wave people over, bow, whatever.
Or you can just use them to look goofy. So far no NPCs have reacted differently to me, but maybe they do somehow though that obviously isn't needed for the platinum trophy.
