This term refers to a specific product category within the sleepwear market: pajamas featuring imagery related to the Dr. Seuss character, the Grinch, sold by the retailer Target. These products are typically sought after during the holiday season and are associated with festive attire.
The popularity of such merchandise stems from the enduring appeal of the Grinch character and the widespread recognition of Target as a major retail destination. Offering themed sleepwear provides a seasonal revenue stream for the retailer and caters to consumer demand for holiday-specific products. This aligns with broader trends in character licensing and the commercialization of popular culture, particularly around holidays.
