shit sandwich breath
When someone opens their mouth to talk, and the smell is so rank, it smells like they ate a shit sandwich. They have shit sandwich breath.
Damn, Alan! Your breath is the worst! Smells like you have shit sandwich breath!
Shit breath sandwiched
Having to sit between two people who's breath smells like they've eaten a dead festering skunk that's been deep fried in camel shit.
I arrived late at training today. The only seat available was between Houghton and Coughlan. I was truly shit breath sandwiched. They nearly melted my face off when they started talking to each other.
