Having been labelled "fucktard" by bubba, I'd rather you didn't use that term as I don't wish to be lumped into the same category as those people that are crying for their toy to be fixed immediately. Rather, terms such as "scatboy," "bottomfeeder," "knuckledragger," and "shitheel" would probably be sufficient for your purpose, and leave we legitimate "fucktards" out of this particular picture.
Thanks!
