I couldn't find my 32 yo Russian Dictionary (I suspect Bethany absconded with it, now that she has some TaTu CDs in the original Russian :), but according to my Russian for Beginners book, babushka just plain means grandmother. This book doesn't have English-Russian equivalents, and it was interesting to have to read Cyrillic again. Been full many a year.... Holly former US soldier / Russian linguist during the Cold War--I can remember tyagach and samaleot just fine (guessing at how they would be transliterated--don't know how to render Cyrillic on a Roman keyboard), but I had to look up babushka--bet ya can't guess what the others are! :)
