1) a fetid smell that applies to one stench alone: that of catshit. thus and so since the crunch-stench of a witch's familiar causes a distinct "*crunch* my god would that i'd be elsewhere in the nick of time... to avoid this *crunch.*"
on a molcular level or, as certain departments would have it, what it actually happening here is the high iron content typical in the diet of a cat is acting like a bastard on the palatte, not only grating whatever, fags booze or aged cheese eg stilton is on there of the sufferer to begin off, but also dressing the wound with shit particles.
2) the derivative of what it is to be bested
having consumed ~yard of purple tin (and this applies to BOTH definitions, not that we all don't enjoy a good listing) steve-dave for some reason stepped outside to piss, i mean like this is outside his own house, to be greeted right (your left) templewise with a bastard. down he goes, into the local witch's familiar's ~week, ~week 1/2 old shit.
ooooh... now that's gotta crunch-stench.
