Be boring rather than arrogant. If they ask what you did this weekend or what you’re doing later just say nothing really or watching TV and relaxing. Few words answers, when the conversation isn’t flowing naturally they will just think you’re boring and leave you alone.
Obviously this might not work for everyone but it’s worked for me everytime.
I’ve seen some that follow other accounts around and comment on everything they post/comment because they’re salty about an argument in another thread. It’s strange to say the least.
