Y'see, beskar'gam, dikut, ner vod & words like that are part of the new Mandalorian language that Karen Traviss, author of the Republic Commando novels, developed for LFL. It's a real complicated language & even tho I consider myself somewhat of a hardcore Fandalorian, I just haven't bothered to even try & learn it other than a word here or there. People are learning it tho, there's Klingon comparisons going around & it's muy geeky to talk to each other in Mando'a in public. Still more power to the geeks inside for those that're learning it.
