not sure what you mean... do you mean goriest horror 'movie' moment i've seen, or the goriest horrific thing that's happened to me? well, i'll answer both:
goriest horror movie moment - the lawnmower massacre at the end of peter jackson's Braindead.
goriest horrific thing that's happened to me - well, once i bladed my forehead on purpose (LONG STORY!) and i accidentally cut too deep and practically went down to the skull. i blead like hell and almost passed out. it required a dozen stitches. i was completely crimson from head to toe! plus i had to explain to the nice people at a&e that i was a time-waster as it was self inflicted.
