'Clean bandit' (чистый бандитка) - would a normal Russian speaker understand this to mean 'total rascal'?

Question

The British music group Clean Bandit take their name from the Russian 'чистый бандитка'. Grace Chatto, one of the band's members, says that a Russian lady used it to mean 'total rascal'. She mentions that it's not common slang, however:

"It is not actually a common phrase that Russians use," Grace explains. "There was a lady who was quite inventive with language who said it. And she described my sister as a 'clean bandit,' like, a 'total rascal.'"

The only mentions of 'чистый бандит' I can find are in relation to the band. Would an average Russian speaker understand 'чистый бандит(ка)' to mean something like 'total rascal'?

Answer 1

There are two variants of what they say.

  Чисто бандитка.
  Чистая бандитка.

чистый it's not something that we talking about the feminine.

Чистый sounds very similar to чисто, people seem to have confused the words.

I suppose it is чисто бандитка.

Чисто is adverb. A full sentence is abbreviated as Чисто бандитка. The full sentence is:

 
          Она есть чисто бандитка. 

  She is clearly a harum-scarum child, wanton.

Answer 2

"Чисто" is an anverb, as had been said already.

"Чисто" doesn't mean "clear" (without stains or flaws) here. It is quite specific to the slang of bandits from 1990s. So it's meaning and connotations are

1. 50% "truly, absolutely, definitely"
2. and other 50% "I'm a bandit from Russia's 1990s, yo, moth****cker!".

"Чистый" is not a slang word, but it belongs to spoken language too. It also means "true, total". Possible alternatives to this word are:

Форменный бандит
Настоящий бандит
