Post shit that makes you cringe! Let others be disgusted by what disgusts you (or let them get a hard-on by what disgusts you because they have some kind of repressed desires)!
For me, there was this programme that used to air on TV back in late 2008 and early 2009. It was entitled "The Marvellous Misadventures of Flapjack" and it has to be one of the most disturbing cartoons I've ever watched (okay, maybe not as disturbing as Ren and Stimpy
). The following review sums up a typical episode of Flapjack.
Speaking of disturbing . . . there's this website called Fluffybooru
. It's a website dedicated to posting stories and pictures of imaginary sentient horses that can speak English with the IQ of a 3-year-old getting tortured in the most brutal of fashions. I got linked to it on 4chan one time when I was browsing /mu/ (the Music board). I had nightmares for weeks.
