Waiting to show a good hand

I see this a lot. Some guy bets on the river and gets 2 or 3 callers. Then he just sits there waiting for them to show first. It seems to be some type of game they play.

If the last bettor or raiser stalls, why doesn't the dealer or some other player(s) pipe up and ask them to show. People will probably get the idea after they've been asked a few times.
