Zonga on its own is a word that defines the movement of expertise or performance level of an
individual. Basically meaning, moving to the next level where the audience know of the level, and occasionally experience it and get hyped up. If you duplicate the word, as in Zonga Zonga, this would
mean the individual has gone beyond the next level. So, its really someone who knows his/her
field so well, that they can produce results beyond the expectation of the audience.
A typical example (although not strictly associated with) would be a
DJ set. The
DJ can be playing a mediocre mix-set, and then branch out into new territory - this is known as Zonga. But if the
DJ then reaches deeper into another level of unknown territory, this is where Zonga Zonga comes into its own.
