I'm going to call a girl fat when she was roasting me.
Why would you be so mean to her?
Because I hate her attitude towards me
I understand, but it's not cool to insult someone's appearance. You should learn to just ignore her.
But I'm going to do it anyway and make my point clear. The shit is going to hit the fan.
Come on, insulting people's looks isn't a nice thing to do. Would you want her to do the same to you?
