A style of demin shorts or pants that are usually sagging. They tend to be either dark demin (navy, black) with a lighter color of demin in an oval-like circle that look like it's been spray painted or a light blue color demin with a white spray-painted look. Black people and a wigger tend to wear these.
Person 1: Hey man, why does that guy's pants look like they've been changed to a lighter color near the knees?
Person 2: It's called a sandblast
