baka..... japanese for stupid... or fool. My buddy and I joined a competitive DoD team for CAL back in 03 and since our class was support(the meta has always been 2 supports on a 6 man team), and since we always worked together as a tag team we decided to name ourselves baka and ahou(which means more or less the same thing). It has been our names ever since then. We even call each other by those names when we hang out lol.
