style of sunglasses, or stunna shades, made popular by rapper, kanye west.
metal (sometimes plastic) glasses complete with slits cut out horizontally; not unlike window shades or "shutters", but do not actually have any glass or translucent plastic for lenses.
origin could possibly be derived from eskimo sunglasses used by whale hunters.
also, could possibly be the worst trend of 2008. shutter shades do absolutely nothing and look ridiculous. thanks, kanye, you've doomed us all.
kid on street #1: daaang you're shutter shades are bitchin'.
kid on street #2: yeah man, they do nothing so you'll probably loose your vision at an early age. thas tiight!
