Spew
To spew is to give away chips by playing too many hands and betting or calling too much, usually while angry. A player who spews makes many bad plays in a row.
The simple explanation
Spewing means losing chips through reckless play. It often follows a bad beat: the player is upset and starts calling too much and bluffing too often. Players say 'he is spewing' when they see someone do this.
A closer look
Spewing is a result of tilt, and it is one of the most expensive habits in poker. Opponents can exploit a spewer by playing strong hands and letting him make the bets. The fix for your own play is simple but hard to follow: take a break, set a stop-loss and avoid playing when you are angry or tired. Spewy plays also happen without anger, for example when a player is bored.
A practical example
After a bad beat, a player starts raising every hand and calling large bets with weak hands. The others say that he is spewing.
