A player who plays in the worst possible way, constantly annoying others while entering almost every hand, shows a lack of respect not only for the game but also for themselves and the other players. They’re not interested in playing properly and often try to distract or tilt their opponents instead.
That said, once you understand how these players think and play, they can actually become very profitable to face. Against someone like this, you’re happy to get all in preflop with a hand like pocket aces, because they’ll often call with much worse. Sometimes they’ll get lucky, and that can be frustrating, but in the long run the balance should fall on your side if you keep making good decisions.
