Tactic developed by Sir Christoff Wagenaar as a means to undermine and defeat rival fans, haters, or just plain people you want to humiliate. You go to My-Banners.com and find or make a banner that you know the person will hate, then upload it and tag it to their page, leaving a banner across the top. BOOSH!!!
