I don't think you should be sad that you're not good at that stupid fucking game. Everytime I walk past an arcade and I see people jumping up and down on little colored squares, I laugh my butt off. Of course, the phrase "you got served" meaning that the person saying so is a better dancer than the person it is said to, is the dumbest fucking thing on the planet. It reminds me of Westside Story, and that Michael Jackson video, and all the other pop culture, "lets-dance-instead-of-fighting" shit. Don't feel bad that you aren't good at something that is stupid.
