The hazy feeling one gets after spending too much time shopping at large chain stores including but not limited to Walmart, Home Depot, and Bed, Bath and Beyond. Characterized by a headache, dry eyes, blurred vision, blank stare, sore feet.
Jane had to return home immediately, take two tylenol, and a large glass of water as her day of shopping was beginning to result in a textbook case of mass merchanditis.
