Pik-Kwik Feet
noun: refers primarily to white trash who's feet are stained a dirty black color from walking everywhere barefoot. Commonly also known as soot foot, blackfoot or 7-11 feet, Pik-Kwik Feet just sounds funnier and in places where Pik-Kwik was a local convenience store this version of the noun was often used instead of 7-11 feet or having a blackfoot sighting simply because it rolls off the tongue easier. Either way if you have 7-11 feet, soot foot or Pick-Kwik feet it means you need to not just wash, scrub & exfoliate your feet your stanky feet.
By the time I got down to suck on her toes I quickly stopped because the bitch had some stank ass Pik-Kwik feet.
