dun 

Part of the Queensbridge version of the "Dun" language in which words that begin with the letter S are replaced with the letter D so long as it doesn't create another already existing word. Other examples of this language are the words: dolo, doopid.

Dun 

Dun simply means "son". Originally started from a handicaped kid in Queens, NY. He couldn't pronounce son, so everytime he said son, it sounded more like dun. Mobb Deep coined the word and still use it today!

Yo! what up dun?

Dun 

Originally used in greeting those who names are unknown to you or have been forgotten, dun has been revolutionized to act as a comma or pause in a sentence, indicating also that the following part is of significance and those around should stop what they are doing if possible and pay close attention. However "DUN" is also used when speaking with close friends and can take on several positions of a sentence.

"Ayo where ya going dun"
"Ayo dun, we bout to go down the road and handle buisnes"
"wassup dun" "safe dun"
