What does buffy mean?
Buffy is an adjective describing something tinged with buff — a soft, pale yellowish-brown color named after the hue of buffed leather, which itself takes its name from buffalo hide. The word is most at home in natural history writing, where ornithologists and entomologists use it to describe the warm, sandy tints of feathers, fur, and insect wings, as in 'a buffy breast with fine streaking.' It also has a place in medicine: the thin whitish layer of white blood cells that forms between plasma and red cells in a centrifuged blood sample is known as the buffy coat. Outside these technical settings, buffy is uncommon and can carry a lighthearted tone, sometimes used informally to mean physically fit, by analogy with 'buff.' Its friendly sound and association with the familiar given name give it a whimsical quality, but its core meaning remains firmly rooted in that gentle tan-cream shade found throughout nature.
Tinged with buff; of a light yellowish-brown or cream-tan color.
"The sparrow showed a faintly buffy wash across its flanks."
Especially common in field guides and zoological description.
Informally, muscular or physically fit; having a toned physique.
"He spent the winter getting buffy at the climbing gym."
Casual and humorous; 'buff' is the more common form.
Before Buffy Summers slayed vampires, 'buffy' was already in the dictionary — it's the color of dried buff leather, and doctors still call the cell-rich layer in blood samples the 'buffy coat.'

Etymology of buffy
Buffy derives from buff, the pale yellowish-brown color named for the undyed leather made from buffalo hides, which became popular garments in late sixteenth- and seventeenth-century England. The suffix -y simply turns the color term into an adjective meaning 'tinged with buff.' English words sharing the ultimate root include buffalo, borrowed through Portuguese from Asian languages, and buff, which also gave rise to figurative senses such as an enthusiast ('a film buff') and slang for bare skin ('in the buff').
