The Luigi Mangione meme emerged following the arrest of the primary suspect in the 2024 shooting of UnitedHealthcare CEO Brian Thompson. Images of Mangione smiling during his arrest, along with excerpts from his alleged anti-corporate manifesto, quickly spread across social media platforms. The meme template is primarily used to express dissatisfaction with the American healthcare industry, often framing the suspect's background as an Ivy League graduate turned radical figure. While the subject matter is controversial, the internet's reaction has transformed the imagery into a viral vehicle for 'Eat the Rich' sentiment and systemic critiques of corporate health insurance practices, making it one of the most polarizing and trending templates of the year.
