shart mouth 

Somebody with really bad breath. Breath so bad that it wreaks of a faint hint of shit.

Omg. I was talking to Bob and his breath stinks. I can't handle having that shart mouth anywhere within my immediate proximity. That shart mouth should just keep his trap shut.

Mouth Shart 

When you burp and you get the taste of puke. Similar to a shart, where one farts and a little shit comes out, but in the mouth area.

Guy 1: *Burp* Oh shit, i just made a mouth shart
Guy 2: Aw, you want some Sprite?

Shark Mouth 

The smell of someone after drinking the bright yellow energy drink Shark, manufactured by the geniuses at Shark AG. A cuttingly sweet saccharine disease ridden aroma. What people with leprosy would probably smell like if they had munched sugar until their rotting teeth had dropped from their oozing gums.

What the f**k, your Shark Mouth has knocked my guts splashing.
