Sewer Mouth 

The disgusting taste that you get in the morning on wake up. Ofter accompanied by a compelling need for a drink. This feeling is experienced most mornings but is intensified after a heavy night of drinking or after a curry.

Text 1: Hey man...how good was last night!? Had such an amazing night
Text 2: Yeah it was pretty good but the curry followed by drinking gave me the world's worst sewer mouth....
Text 3: Yeah ditto...

A European. It is unclear if they do not have access to tooth brushes, or if they just refuse to use them. However, for one reason or another, they manage to have the most disgusting teeth on the planet.

"A sewer mouth just joined our game - you can tell because he spelled 'Jail' as 'Gaol' "
"Why are people from Europe so annoying?"
