That's me, Jrlz, holding up the "Jefferswag" sign behind Desmond Howard at College GameDay in Atlanta. I had been using it earlier, but this, I believe, was the moment when "Jefferswag", which I had been using amongst my friends since the season prior, gained infamy.
WHY, did I begin this trend, you ask? Well... I have absolutely no idea. Oh well. But next time Jefferswag pops into your head (it happens), be sure to thank me.
UPDATE: WatsonTiger wants props for making it popular. Thanks, WT.
