twerp

In my unending search for alternate curse words (to employ mainly while behind the wheel) it recently occurred to me that twerp might be a good choice, as opposed to jerk, idiot, or worse. Twit is also a contender.

Any other suggestions?

I know I first hear it from my dad, who may also have been looking for less colorful language. Not sure I buy the Tolkien association offered by Wiktionary. That seems altogether too twerpy to believe.
