Horrors, I’ve had my collar fingered by the Thought Police! 
If I may be permitted the right of reply, may I submit this data point:
The OED defines “twit” in this context as “A fool; a stupid or ineffectual person. slang.”
This is especially amusing as Dr Smith (before even completing her PhD) was able to prove Michael Behe (who Eddie was attempting to defend) foolish, stupid or ineffectual on the subject of virology. I would further note that this seems to be a trend, and it is hard to think of a biological field that Behe hasn’t proven himself to be foolish, stupid or ineffectual on. On this very forum it was demonstrated that he was foolish, stupid or ineffectual on the issue of good judicial practice, and at his cross-examination at Dover, his infamous Astrology admission proved him to be foolish, stupid or ineffectual on the Philosophy of Science.
I will leave readers to decide for themselves who the real “twit” here is.
