An event, usually held in garages, which is usually advertised on the side of the road or on telephone poles and also in the classified ads, where bargain shoppers can go to buy used junk, which they will later decide to get rid of. So, they decide to have another garage sale of their own, so they can sell all the junk that they bought at other garage sales.
It is strongly advised not to wear any clothing purchased at garage sales, nor eating utencils. Besides, would you eat off of a plate that you bought from a complete stranger? Well, hell, if this was the case, then there's not really much you can buy at a garage sale.
