Velociwanker

A velociwanker is a term specially reserved for those pricks who achieve full wanker status, with all the ferocity and speed of a velociraptor. 3 or more velociwankers (plural) can give a Tyrannosaurus Twat a good run for their money, in terms of being an all-round prick.

People who live solely to write negative comments on posts, with no purpose other than to be a prick, are massive velociwankers.
