These vehicular accessories visually represent allegiance to two different, often rival, entities, most commonly sports teams from different universities or geographical areas. For example, a vehicle may display a graphic that is bisected, showcasing the colors and logos of two competing college football teams, indicating the owner or occupants support both.
The significance of such displays stems from their ability to publicly express personal affiliations and passions. They act as a conversation starter and a form of self-identification. Historically, these emblems have gained traction as a lighthearted way to express potentially conflicting loyalties within a family or household. Benefits include fostering a sense of community among fans and providing a visual representation of shared, yet diverse, interests.
