You could add that the answer to Bog daj! is Bog lonaj! Since the fisrt one means (Let) God give! the other is (Let) God bless (it)! In Upper Savinja region the various Bog ____! (or Boh ___! to be fair) are still popular with the older generetion and it's considered rude not to respond right. So someone greets you Bohdaj! you answer Bohlonaj!

Bohmarije and similar are poular elsewhere too! ;)
