cretin 

A Person that is: brainless, stupid, child-like, and full of pointless information that makes no sense and appeals only to other cretins. They can be found in abundance in every single populated internet forum, where they race to post as many mind-numbing messages as possible in a single session. In addition, they seemingly interbreed with other cretins, ensuring that their cretinous genes continue long after they end up dead meaning the Internet will never be rid of their kind. More's the pity.

Jodie and her friends like to post messages on forums about how cool it is to kick cats down stairs and throw banana skins at hungry tramps. Clearly they are cretins and should be eradicated from existence.

Intellectual: "You're rather cretainous, aren't you?"
Cretin: "HUR?"
