When someone takes a hit while driving and gets smoke in their eyes causing them to go blind for a few seconds. this is a very dangerous disease that has plagued stoners since the invention of the automobile.
driver: Bro pass the blunt!
passenger:Here man it's roasting
Driver:(takes a massive hit way beyond his smoking abilities...so smoke goes everywhere) FUCK! Drivers blind we're going to crash bro!!
passenger:(becomes a stoned hero and grabs the wheel before they crash) I got you bro.
