What does northeast dialect mean by batting practice?

Hey, Northeast dialect is really nice, haha! Do you know that?/You know what? But then again, it's really not a good thing to hear someone say that you need to practice your Northeast dialect. What this means is that something you do makes people very unhappy and dissatisfied, and you are ready to be beaten.

This statement is extremely regional, and you can only hear it in the northeast. Ask your friends elsewhere. But then again, the northeast people are also famous for their hot temper. If they really meet someone who needs batting practice, they may just start working.

Of course, we should pay attention to the scope of application of this statement. Not all people in the Northeast will use this expression, and you can't copy it mechanically. Don't use it indiscriminately in other places to avoid making jokes. However, in the era when the mouth is getting more and more broken, things like pranks can be seen everywhere, and you need to pay attention to what you say.
