Since you can be called friends, it must be something that happened before that made you feel good to each other. Now you think he is an annoying friend, or maybe you will feel this way about him because of something. You can analyze whether your idea is correct, because after all, you can be friends once.
If you want to get rid of such a friend, you can simply tell him that you may be too busy to talk and chat with her in the future, and then let him get in touch with other people around him and find his new friend. When he asks for you, you can tell him that you have something to do, so that he will think that you may not want to help him anymore, which will also alienate your relationship, and your annoying friend should choose slowly. You can also get rid of your emotions in another way, because you think he is annoyed recently, maybe because you misunderstood him on some things. You can also carefully evaluate whether this person is really annoying. If you misunderstand your friend just because of your recent mood, then I think it is a pity.
Don't use excessive language to stimulate others just because you are particularly annoyed with this friend recently. You can tell him in a silent way that you don't want to be friends with him, or you can think carefully about whether you really misunderstood others. You should be kind to every friend around you and don't let yourself regret it in the future.
