This reminds of the conundrum which goes something like:

"Do you enjoy beating your wife?"

"Yes" means that you beat beat your wife and you enjoy it.

"No" means you beat your wife, but you don't enjoy it, sort of doing it out of
a sense of duty.

"Mu" means 'I deny the premise of your question', i.e. I don't  beat my wife
(the set of events of I beating my wife is null).  Mu as I read about it
is supposed to be of Oriental origin and would be the appropriate response
to .i piro loi pavyjirna cu blanu vau
