a term to describe an anatomic quality of a woman in which during the act of fellatio, there is disambiguation of where the tip of the penis ends and where her mouth begins, likened unto putting your cock into an incredibly soft pillow.

"Marble Mouth" is a slang term used to signify people who possess a slight speech impediment. It's hard to describe, but it certainly has nothing to do with location or cultural background like one definition ridiculously stated. It's not that they stutter - they don't necessary. But it's obvious that speaking is not their strong suit and they sound as if they have a mouth full of marbles. Marble mouths, more than anything, are highly annoying because you just want them to spit the words out already.
Eli Manning. A perfect example of a marble mouth.

The type of mouth you get after a night of heavy drinking and taking drugs in excess of number. It consists of a sticky velcro tongue (so sticky it could stick to a dogs bollock and you get a dog fart in your face), a dry cloggy throat that's 1mm wide, furry teeth and lips that have flaking peeling dry skin coming off. It also creates a mouth that is non-quenchable by any liquid, it even makes ice water taste like you're licking the inside of a dustbin.
Courtney: My ass mouth is making me wana slit my wrists and dance in my own blood, I wish I had some turboce.
Amber: I'm not suprised, you're breath smells like a decapitated corpse, have a polo.
