Really want to delete him

Last night, my two friends and I were playing in a three-person squad, and someone I met a few days ago wanted to join. Honestly, I didn't really want him to join because he's noisy, tells unfunny jokes, and makes lewd comments, which I really dislike. He's also not very skilled. I don't mind if someone is unskilled; I started that way too. But when you talk, you should either call out positions properly, be funny, or just stay quiet. Or just chat normally and don't make lewd jokes. He did none of that, which really annoyed me. In the end, I let him join because a mutual friend was also in the lobby. If I hadn't let him in, my friend would have. But this is probably the last time I'll play with him. I tolerated him a lot for my friend's sake, but I really can't stand it anymore.
