'Mirin, short for 'admiring,' is a staple of internet bodybuilding culture that originated on the Bodybuilding.com 'Misc' forums in the late 2000s. It was popularized by the late fitness icon Zyzz (Aziz Shavershian), who frequently used the phrase 'U 'mirin?' to challenge or acknowledge those looking at his physique. The meme usually features a photo of someone looking at another person with intense, often exaggerated, respect or desire. Over time, it evolved beyond the gym to represent any scenario involving a look of pure adoration, from pets staring at food to fans looking at their idols. It remains a go-to template for celebrating hard-earned accomplishments or wholesome attraction.
