Made famous by dancing guy on It's Always Sunny in Philadelphia. It's when you wear a diaper and possibly other baby accessories while dancing to some club/techno but be so cool people dig that you're in a diaper.
When Dancing Guy was on public access in It's Always Sunny in Philadelphia diaper time came at random intervals of the show introducing people dancing without a care just in their diapers.
