grout mouth 

When plaque builds up in between your teeth to the point where it looks like you have had them grouted in.

That b**** might be fine if she would brush her teeth but she just such a grout mouth, I can't f*** with her

Mouth Grot

The nasty taste you get in the morning when you first wake up. Usually utterly disgusting especially if you had been drinking the previous night. Culmination of the words "Gross Rot"

I shouldn't have done all those mushrooms last night, I have the most horrible mouth grot this morning.

mouth gout 

That slightly sour, uncomfortable feeling in the bottom corners of your mouth after you‘ve gorged on things like salami, olives, red wine and cheeses and your gums aren’t used to being bombarded with so many rich, salty flavours - so it takes a while for the funny tingling in your jaw to go away.

Hey, why are you pulling those funny faces, what’s the matter with you?

Oh man, I hit the canopes in the other room hard when I got here, I was starving. Delicious - but now I’ve got the mouth gout.

Mouth Gout 

When you leave a little bit of mayo or sauce on the corner of your mouth after eating, and it looks like remnants of sexual activity.

Did you see Steve at lunchtime, he had some Mouth Gout on the side of his face.
