The phrase references a large, often electrically powered, representation of the Dr. Seuss character, the Grinch, offered for sale at the Home Depot retail chain. These decorations are intended for seasonal display, typically during the Christmas holiday season. An example would be a homeowner purchasing the item to place on their front lawn as part of their holiday decorations.
The popularity of such items stems from their ability to create visually engaging and festive displays. These decorations contribute to the overall ambiance of a neighborhood during the holiday season and can become a focal point of home decorating efforts. The availability of these items at a major retailer like Home Depot indicates a widespread consumer interest in large-scale, animated holiday decor.
