Wired Threat Level has an analysis item up about the newly-minted internet meme first shrieked by that Florida student while he was being tasered during a speech by John Kerry:
Just two days after it was yelled out in a University of Florida lecture hall, "Don't Tase Me, Bro!" has become the newest cultural touchstone of our pop-cultural lexicon.
The phrase has inevitably ricocheted around YouTube, various blogs, newspaper Web sites, television network news shows and it's been among the most searched for phrases on Google for the past couple of days. Several enterprising individuals have even snapped up variations of the spelling of the phrase as Web addresses. Someone has created a mashup and a couple of t-shirt designs have emerged. On YouTube, footage of the incident has been viewed more than a million times, and several people have felt compelled to record their own video responses.
