Really pelon just means bald guy, but it IS often used this way. I learned this translation of the term in the unusually good subtitles of the great documentary Resistencia. If you have been outraged at the murder of Berta Caceres in Honduras, one of the things you can do is learn more about the current horrendous situation in Honduras and the movements organizing for justice there. One easy way to do this is watching this great documentary, which is surprisingly enjoyable to watch given the story it tells, and which you can easily rent online here. If you are an interpreter, some choice terms in the subtitles will be an added bonus.
