look up any word, like the eiffel tower:
When your arms are tanned up until where you t-shirt sleeve would start but the rest of your torso is still pale. Named after the phenomenon of agricultural vets sticking there arm up inside animals... Think about it.
I was working outside all summer but couldn't take my shirt off, so I've totally got a vet's tan right now.
