Definition of spewtard
A spewtard player is a "retarded player who spews" (spew + retard = spewtard) in other words, a player who is considered to be an idiot who spews. A spewtard is a spewy player, i.e. he tends to have no regard for his money. The spewy player will be the type to call too much, bluff too much, push all in repeatedly because he is sometimes tilted. The spewy or spewtard player will also be the type to play higher than his means. Against a spewy player, you play solid ABC poker and don't bluff him. You wait for a good hand and let him mug you for your buy-in.
How do you recognize a spewtard?
If you have a tracker like PokerTracker, you will recognize it by its demented statistics. The spewy player will have a high VPIP, a high preflop raise, a high 3bet and an almost non-existent fold to 3bet. Something like 75/55 with a 35% 3bet and a 5% fold to 3bet. Generally, the spewtard will respond to aggression with aggression. He is a gambler; he is sometimes there to have fun, to blow off steam, to bluff. One thing is certain, he is not there to lie down and let his opponents dominate him. Don't bluff the spewtards, wait for your hand and clear them out!
