bobolis to bobolis is incorrectly written and it should be written as "say say" still its meaning:
It is a Latinism formed and deformed from " vobis, vobis " expression used by those who gave alms to the poor in the middle ages, meaning " for you, for you ". This expression became the adverb " of vobis vobis " that turned out to be " of say say " perhaps playing with the sense of bobo and meaning to bobo, bucket, in a free way, without any effort or merit.
