Threshold of Pain ( poker )

A point of losing beyond which it no longer hurts to lose any more. For example, for one player it might feel very bad to lose $900, and even worse $1000, but no worse to lose $3000 than $1000. Consequently, it is very dangerous for that player to get stuck $1000, because he has crossed his threshold of pain and it will not be very hard for him to end up losing $3000. Unfortunately, the $2000 difference will hurt very much the next day.
