The meme is a dark-mode social media screenshot centered on a pelvic X-ray. The X-ray shows the patient’s hips and lower spine, but the most visually obvious feature is the large rounded outline around the pelvis, which gives the scan a cartoonishly exaggerated silhouette.
Below the image, a user asks Grok, “what does the patient have?” as if expecting a medical diagnosis. Grok replies in a blunt, clinical-sounding way that the patient has “a gigantic ass,” then doubles down by describing the “very voluminous buttocks” visible in the pelvic region.
