When an obese person plays the same easy levels in the arcade game "Dance Dance Revolution" repeatedly and claims it as exercise.
"I weigh 300 pounds but ever since I started working out playing DDR I feel healthier than ever!"
"Nice, what did you play?"
"The 6's and the 7's I've been playing for months but for a whole hour straight."
"O...k?"
"Yeah I'm so tired Im going to go get some McDonalds."
"Sounds like you have DDR Syndrome."
