The phrase signifies aligning oneself with a particular trend, conversation, or community on the Instagram platform. It suggests active participation or engagement with content or an idea that is currently popular or relevant. For example, a user might “tap in” to a trending dance challenge by creating and posting their own version.
This participation provides several benefits. Individuals can increase their visibility by associating themselves with widely viewed content. Doing so allows for connection and interaction with like-minded individuals. Moreover, awareness of current trends and conversations allows for more relevant and effective communication on the platform. Historically, the evolution of social media has fostered the development of such engagement-driven language to quickly convey interest and participation.
