Across multiple Major League Baseball stadiums, fans are taking part in a “Tarps Off” trend that centers on removing shirts in designated sections and twirling them above their heads. NPR describes the participation as typically involving groups of mostly young men who join in near areas where the activity is already happening. The basic prompt, cited by outlets covering the trend, is to go to the section where the “party” is underway, take off one’s shirt, and begin twirling it. Other reports similarly characterize the spectacle as a fan-driven display that has spread widely through baseball venues. Coverage frames the trend as both a social moment among attendees and a source of increased attention due to its visibility in stadium settings. While the outlets agree on the general description and mechanics of the activity, they do not present a single unified origin for the practice in the provided excerpts. The reports collectively indicate that the “Tarps Off” behavior is occurring at ballparks in multiple locations and is being noticed by mainstream media as it gains traction among spectators.
