Don't do this.
"Cunt" is an extremely sexist and offensive slur for a vagina. When you use it to refer to someone or something you do not like, you are implicitly insulting all of the women on this board for their sex. That is unacceptable. I realize that this word does not have the same taboo in other English-speaking countries as it has in the United States, but that is not an excuse for using it.
This term is pervasive in football threads on GAF, and while that might have given some posters the impression that either it was acceptable generally or acceptable within these threads, that is not the case. The TOS specifically states that, "Sexual, racial, or ethnic slurs will not be tolerated in any form and are bannable on the first offense."
