"我很酷所以讨厌者不得不让我冷静下来"

Simplified Meaning:

When someone says, "I’m fly so the haters gotta put me on ice," they mean they feel very confident and successful, like they are doing really well. Being "fly" means looking good or doing great things. But because of this, there are people who are jealous or don't like them, so these "haters" try to bring them down or stop them from shining. Think of a famous basketball player who is excellent on the court, making lots of points and winning games. Other players or fans from the opposite team might not like him because he’s so good. They might say bad things about him or try to make him look bad. But he shouldn't let them bother him; instead, he should keep playing well and remember that their jealousy shows that he is doing something right. In our everyday lives, if you are good at something like school, work, or a hobby, there might be people who don't like it and try to stop you or say mean things. But instead of letting them get to you, you should keep doing your best and understand that their negative actions are just signs that you are doing well.
