In general I second what was said above about spewing chips - playing blind is not a winning strategy.

There might be some psychological edges you could cultivate by making this play sparingly, e.g. if you think creating a 'crazy weirdo' table image will work to your advantage or you think your opponents are going to go on tilt when you do this for some reason.

The other exceptional case I can think of is if you're playing against someone who can read you at a near-telepathic level. The correct move is to get up from the table, of course. However, if you must continue playing for some reason, you will lose less money if you (and therefore your opponent) don't know what cards you hold.
