Popular social media content, which is liked by a large number of people, although seemingly trivial, can reveal important information about the modern world through the application of scientific methodologies. Understanding the popularity of certain trends on social networks shows us the social aspirations, that is, the aspirations of contemporary social reality. The "That Girl" trend indicates social aspirations in a wider cultural context. Analysis of content, social networks and cultural criticism of the trend provided a broader perspective in which human values are deeply influenced by deeper structural relationships. The "That Girl" trend shows how individuals are motivated to adopt new values and habits not so much from an internal need for change, as from a desire to respond to collective pressures and norms promoted through social media. In this dynamic, values such as self-help, productivity, and health become idealized to the point that they often ignore the actual social and economic circumstances in which most people live. Moreover, such trends reveal a problematic dimension of contemporary society where the experiences and identities of individuals are commodified, turning into products that are consumed and evaluated on the market of social networks. This process obscures deeper structural inequalities, as the presentation of idealized lives creates a false perception of availability and achievement. This work is a detailed presentation of a popular trend promoted by social media, which, by applying the mentioned methods, content analysis, social networks and cultural criticism, shows how power relations and ideologies can be seen in examples in popular culture. And what role do they play in the formation of social relations.
