Threadshitting is threadjacking with intentionally vile content which includes extremely NSFW images such as tubgirl, goatse, genital mutilation, murder and anything else that a mature, sane person would find offensive and/or disgusting.
The "Desperate Houswives" thread was chugging along nicely until some b-tard threadshit all over it with goatse.
