It is mainly used for an insult - ''du ma/ duma = fuck your mother''. However if they used this (du ma) along the side with an compliment, this means that your outfit, shoes, etc... (the thing that caught their eyes ) is so astonishing, marvelous, gorgeous that they have no words left to say but just beside a swear word.

Synonym : Most likely would be ''Dit me'' or variations '' Du ma + may''/ Dit me ''may''
