not a worm, just a fungus throwing a circular rave on your skin

means A contagious fungal infection of the skin that produces a red, ring-shaped, often itchy rash — despite the name, no worm is involved.

from A plain old English compound of 'ring' and 'worm,' naming the disease by its two most striking features: the telltale circular rash, and the old belief that such creeping, spreading skin ailments were caused by a worm burrowing beneath the surface. For centuries 'worm' was a catch-all in English for anything thought to gnaw, crawl, or infest the body, so the name stuck long before anyone knew the real culprit was a fungus.
