damdam is a slang they have just invented here in khi . its actually an alternative to the word Kunnii. (hips)
so your friend in decent language ( although its not )
is asking you to give your hips to him 
and hence he says ,
bring me those hips o boy ,
those hips bring them to me .
plus , m not a pushto speaker , but i have an almost daily gig with pathans , so they were keep going on with this dam dam thing and cracking up , so i asked so they told me . i understand pushto a bit as well like really really basic.
rest you are wise what your friend want from you
