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?

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.
