I know what you mean Laurie. 

The waddle walk(love that termonology Eric)  has been around for a couple of fashion cycles.  I think the pants get lower each time. 

If you combine pants on the ground with drop crotch jeans I bet your couldn't walk at all!

At least pants on the ground got us a song and I just checked and you can still actually buy it on amazon. LOL
