The tournament player who didn't practice the course, hasn't looked at the caddie book, and who asks the group on every single hole what the rules are on this hole, where's the basket, how far is it, what's a good line, and so on. (Edit: Or literally asks me what they should throw.)
Dishonorable mention: the tournament player who thinks "the benefit of the doubt" means that any time they misunderstand the rules for a particular situation and are arguing for something they clearly don't deserve, the fact that other players are arguing with them means there is "doubt" and we should all just give in to what they want.
