The phrase describes apparel, specifically a t-shirt, sold at a large retail corporation, Walmart, related to the traditionally superstitious day, Friday the 13th. This clothing item typically features imagery or text associated with the date or related horror themes. As an example, one might find a t-shirt at Walmart depicting Jason Voorhees, a fictional character from the Friday the 13th film series.
Such merchandise leverages the cultural fascination with the date and its association with misfortune. The benefit for consumers lies in expressing their affinity for horror culture or marking the occasion. Historically, Friday the 13th has been linked to bad luck, contributing to its appeal as a subject for novelty items and themed products. Its availability through a major retailer indicates a broad consumer interest and accessibility.
