Hadouken, the new viral internet meme, is way better than the 'Harlem Shake' and — what was the other one called? Oh yeah — 'Gangnam Style.'
For starters, you don't need a video camera, nor background music or an expensive editing software, to Hadouken. A still picture of you and your friends masterfully executing the already legendary fighting/dancing movement (not to be confused with Jumping Jacks) would do.
In addition, Hadouken is inspired in Street Fighter, the 1980s-1990s Japanese video game from where the "hadoken" or "gadouken" movement (which means, "wave motion fist" or "surge fist") was rescued — presumably by a group of Japanese middle school girls (never underestimate the ability of Japanese school girls to shake pop culture up on a regular basis).
No more, "con los terroristas." Thank God!
