I have a friend, Let's call him "Jack" and the problem I have is that ever since he has started watching some YouTubers, he has now wanted to act like them.
If I was to walk down in street he will sometimes yell out stupid words to be "cool" and maybe do stupid actions as well, trying to get attention on him and sometimes he talks about stuff I don't find comfortable, for example, he likes to say "rape" a lot, and I don't really feel happy about that.
I have told him to stop (kinda). When I told him to stop he kinda like, shrugged it off and this happened near the mall and I told him to stop because he was attracting way too much attention for me and my other friends liking. I said...
"Jack, you got to quiet down dude, people are looking at us and well I don't like that" The very next day he was quite calm but within 3 days, he became the attention seeking person I didn't like. I did speak to my mother about this but she did not know what to do, I asked my brother and he just told me to grow up.
I just don't want to sound rude to him or to feel like I am forcing him to change, but ever since he has watched those YouTubers, he has become an attention-seeking person who talks about topics that make me feel uncomfortable.
How can I tell him that he is making me uncomfortable and that he should stop being an attention-seeker in public (because that also brings attention to me in public and I don't like being a scene)?
(BTW Jack and I are around 13 and in high school in NZ).
