Used in discussion of Hebrew Mystics, of followers of the Cabala. Based on belief that certain words, originally Yahweh or God (as known today), were too holy to even say. Therefore Cabala mystics seem to use the custom to "blip" or not say "Hebrew" or "Jewish"; as in blipish rabbis were among those in attendance to unite the worlds' religions."
