What in the blazes are they for ?
Some people, many of them Gallentean, say that the earlobe is erogenous.
Other people, many of them Caldari, say that the earlobe’s numerous blood vessels are to keep the ears warm in cold weather.
Some more people, many of them Minmatar, say the earlobe is mostly just for hanging your earrings from.
These explanations are mostly cultural, and are not conclusive proof of the true purpose of the earlobe.
Truly, an enduring mystery.
