A good name for a politician.
People found out who the real blowhard was, and it wasn't a politician, it was the girl from next door that thought she was bad, the baddest thing on the block. No wonder her own family had called her mouth of the south growing up.

A very blunt, often humorous way of telling someone to stop talking, usually when they’re being annoying, repetitive, or saying something obvious. Similar in meaning to “shut the fuck up,” but slightly emphasizes the “mouth” for extra effect.
