Swish Pants 

A style of pants, typically worn by school kids, gym rats and street people, that make a swishing sound as you walk.

Mike wasn't allowed to enter the bar because he was wearing swish pants.

Swishy Pants 

Swishy pants are those athletic pants that are very loud and obnoxious when you move around in them. They are very out of style, so don't wear them to parties or social gatherings. Oh and we can all agree that they're a little gay.

1. Google search swishy pants if you want to see them!

2. That dude wore swishy pants to a party, he's got no style.
