Definition of trashtalking
In French, trashtalking could be translated as "langage ordurier". At a poker table, when a player insults you, calls you names, intimidates you, scorns you, makes fun of you, he will be called a "trashtalking". The "trashtalking" is much more common in online poker than in live casinos. People are much more likely to insult other players at the table in the anonymity of online poker than in a casino. If a player makes an trashtalk to you, just ignore them.
Is trashtalking a good strategy?
Poker legends such as Phil Hellmuth are known and recognized for their "trashtalk". He is remembered for his famous insult to a "You can’t even spell poker" player (you don't even know how to spell the word poker). Is it a good strategy to intimidate your opponents? You may be able to get some players to play badly against you, but in the long run, you're going to get confused about how they react. For example, if a player pushes all in pre-flop right after you insult them, is it because they have a good hand or because they are thunderstruck by your insult? Keep it simple and don't make a trashtalking.
