shitsale cowboy
n. A person who wanders flea markets, yard sales or other junk sales in boots, jeans or overalls, and the required cowboy hat. "vintage" (worn out) rock or country tour t-shirts are common. Unkempt, hairy appearance is a must. This person may smell of beer and cigarettes. He or she will never buy anything but may offer a ridiculously low bid on an item just to appear to have money.
I can smell that shitsale cowboy from 50 feet, and he'll probably offer me $5 for this tool box too.
