A woman so fat and grotesque that her gelatinous sacks of tit flubber create a cleavage "death valley" of sorts, extending lower than thought possible before the advent of the phrase "super size me". Simultaneously, twin travesties of repugnant flesh create an unholy "camel toe" or "mooseknuckle" or "holy fucking shit stab my eyes out immediately" extending unnaturally far north and actually coming in contact with the aforementioned "death valley". This creates the nightmarish trench of fear and loathsome disgust known as a "Walrus Muzzle".

Ryan: HOLY FUCKING HELL THAT IS DISGUSTING AND... (stabs own eyes)
Jesse: ... (stabs own eyes)
