Verb: Named after a particularily racist and bigoted user on the imdb forums. This refers to the practice of composing a single long,post and then using cut-paste to spam the boards with it without provocation. This can involve a month-old post or a new one, but it is generally used when the person in question keeps posting the same ramble over and over again, instead of using actual language.

Also called Kleining
"Would you please stop kleining all over the place? Post something different."
