"utterly irredeemable waste-of-space" is also exquisite! i am greatly in favour of broadening my working vocabulary by adding inventive insults.

just that i also need some short, sharp ones, because "stupid" has such a great cadence. that's why "git" is so good, and as you said, it can easily be extended. i like "rotter" too, but that's definitely a briticism. or "dolt". or "blockhead".
