I'm going to call my 'posh' friend inbred and say they have webbed feet.
Why would you say that to a friend?
Because the lot of them are so stuck up. They think money is everything in life.
Just because you don't like someone doesn't give you a reason to be mean and insult them. Making fun of them will just make them feel bad and dislike you. It will also make your other friends see you as a cruel person.
I don't mind, I don't have to worry about anyone disliking me.
Even if you don't care about that, you shouldn't want to hurt people. If their being stuck up bothers you, then hang out with other people.
