Mouthy Broad 

A particularly loud, obnoxious, or opinionated woman who freely shares her (often under-informed) opinions.

Lindsay keeps trying to tell me that she knows more about sports than I do, what a mouthy broad.

A voluptuous biotch that can't and won't keep her mouth shut when it comes to telling people like it is. Especially when it's something you don't want to hear or will make you cry.

The group of fat mouthy broads told the blonde bimbo panties weren't meant to be used as ankle warmers.
