The Noob Switchfoot
when a noob to DDR decides to try and be full of himself by attempting a song on heavy. when this doesn't work out and he is seconds from iminent failure (usually about a quarter of the way through the song), he has a noob buddy try and take over in desperation. This whole act usually ends about halfway through the song.
look at those sad little noobs on max 300. Get ready, when they pull The Noob Switchfoot, shank the first noob with a toothbrush. Then put your quarter up on the machine.
