The original definition is slowly being replaced by the grime definition. Dunno or Dunn'no is referenced after or during a saying of which the general public are assumed to not knowing - hence hightening your reputation on the mere basis that you know something others dont.

It is also known as a "big up" or shout out.. "Big up wiley, dunno"
"Dunno the youth... dunno the youth" (pronounced - Dun'No)

Get the dunno mug.
A term used when a person has been asked a question and doesn't know the answer. Equal to "I don't know", or alternatively "I don't have anything to say, so shut the hell up".

Often overused by people whose minds do not have the mental capacity, or cannot be expected, to think of something for themselves.

NOTE: Never say "dunno" when you have been kidnapped by a bunch of bearded and smoking thugs. You can promptly expect a hard kick in the balls.

Short for 'Don't know' also an acronym for 'Do U Need No Opinion'.
A common reply when the asked person feels that there will only be disagreement or required effort if they give an answer.
Do you think this is the best way to get there ?

(Slang) don't know
You can use it as the same pronunciation such as these sentences:
I don't wanna (pronounced/ I du wanna)
I don't feel (pronounced/ I du feel)
I don't think (pronounced/ I du think)
Notice: (I don't/ don't ) - pronounced- (IPA:I du/ du) as a fast American accent
In some other languages the soft "D" sound pronounced like the "R" sound
So (I don't) pronounced (IPA: I rʊ )
And (don't) pronounced like (IPA: rʊ )
