The 'Long Boy' meme primarily celebrates animals with exceptionally long features, most notably the Borzoi dog breed or the classic 'Longcat'. While Longcat dates back to the early 2000s as one of the internet's first Photoshop-battled pets, the modern 'Long Boy' aesthetic surged with the viral 'Didn't I do it for you?' trend featuring the Borzoi's elongated snout. The meme captures a sense of elegant absurdity, often highlighting the physical distortion of animals for comedic effect. It is widely used to express loyalty, weirdness, or simply to appreciate the 'lanky' nature of pets that seem to defy normal proportions.
