You know how trends start? Someone just does something, a lot. It doesn't even have to be cool. Or accurate. Take Joe Biden, for example. Biden used the word "literally" so many times in his speech at the DNC, last night, that it literally began trending on Twitter, reports the Washington Times. Literally.
The Obama 2012 team even went so far as to buy out an ad on the search term "literally" so as to direct inquiries towards the @BarackObama Twitter handle.
