Soilmouth

An uncommon slur people who eat meat (aka bloodmouths in the vegan community) used against vegans who try to enforce veganism onto other people who are not interested in veganism.

Sidmouth 

The single greatest place in the history of mankind.
Sidmouth is a seaside town with it's very own sewage plant. Local attractions include Carina's, Sidmouth College and 'The Byes'.

Not without it rough parts, including murder, rape and drunkenness, Sidmouth is cultural melting pot with immigrants and locals working together in the towns booming hotel trade.

So? Where are you from?
-I'm from Sidmouth
Oh!? The single greatest place in the entire world!

Shitmouth

Really, really bad breath. Breath that smells like a small animal has died and decomposed in someone's mouth. The type of breath that makes you gag when someone with it is standing within 3 feet of you.

A Shitmouth is a liar, a BAD liar.
Someone who will maintain their lie was true, even when they're trumped by evidence.
