CARRiON.FLOWERS: When someone is being a cunt, you should call them out on being a cunt.
Brasas: A bit sexist no?
Also, in words you implicitly approve: "Get some balls and say that to my face..."
I am joking of course.
Sexist? Nah. I hate every race, gender and religion equally! :]
Also in my own past experience, most people that are trying to bully you will back off when you show them you won't take their shit. The few times they don't, well, if it's time to get ready to take a few on the chin so be it. I'm well aware that last part is probably not everyone's attitude though.
Obviously calling people out on the internet doesn't (usually) lead to such situations but I still say if someone is constantly talking shit or harassing you, call them out.
