I mean, in this case, yes, but I am neither Russian nor a child of the USSR, and I know both Kvass and Kin-dza-dza (which I introduced to my wife, who was born in a post-soviet state). Not all that obscure!
My headcanon is that this is from that time David Lynch defected to the Soviet Union with a briefcase full of film rolls from his ongoing Frank Herbert project. Дун was quite popular in theaters.

Too obscure.
