this is an interesting thread, since I 've been seeing it a lot at $25 NL at FT. However, be careful IMO about trying to make a rule on what to do or what it means. One night, it seemed more rocky play, another night, more moronic loose/passive.

Either way, it IS a sign of poor play right? And, I think it is either sign of a tight/passive bluff or loose/aggressive slow play. So, just look for other clues about the villains play and exploit it with solid poker.
