The phrase refers to user-generated visual content, specifically in the Graphics Interchange Format (GIF), featuring a character named JJ Maybank using a cellular phone. This content is hosted and shared on the Tumblr platform, a popular microblogging and social networking website. Typically, these GIFs capture specific moments or expressions related to the character interacting with a mobile device within the context of a television show or other media. For example, one might find a short, looping animation of the character texting, talking, or reacting to something on their phone.
The popularity of such visual content stems from the ability to quickly and concisely convey emotions, reactions, or plot points related to a character or scene. Fans use these GIFs to express their appreciation for the character, react to events in the show, and engage in online discussions. The historical context lies within the broader culture of fandom and online sharing, where visual shorthand and meme-like content facilitate communication and community building among enthusiasts. The Tumblr platform, with its emphasis on visual media and easy sharing capabilities, serves as a natural habitat for such content.
