the only joint that makes you yelp when bone meets electricity.
means The joint where your upper and lower arm meet, letting the limb bend.
from From Old English 'elnboga,' literally the bend ('boga,' a bow or arch) of the 'eln' — the ell, an old measure of arm-length from elbow to fingertip. So an elbow is, at root, 'the bow of the forearm-ruler.' The 'boga' here is the same word-family that gives us the bow you shoot arrows from and the rainbow — all things that arch.
