Rambutan comes from the Indonesian "rambut" meaning hair (particularly hair on the head, body hair is bulu). This page (http://www.globalgourmet.com/food/special/1999/asian/rambutan.html)has a picture showing two rambutan - one unpeeled and one half-peeled. I'm not sure about her text. Possibly it's specific to Malaysia.

A friend who'd worked as a nurse on a men's surgical ward told me that if you open up a rambutan that's what the inside of testicles look like but I don't know if I believe her.
