iyi aksamlar herkese,

I´ve noticed it quite a few times on facebook, but I have no idea what it means and can´t find the meaning for it. Can someone tell me what, ´yaw´ means. Is it a slang word?

simdiden tesekkurler

It is the broken form of  “yahu “   ya   hu !  -à  Ey  Allahım [ yāhū ياهو]

Different versions are seen in slang “ yaw, yav, yahu ”

Yes, it is slang and may mean ;

·         man !  ,  hey ! ,  for  God’s  sake !  , look !

Ne  yaptın  yahu ? -à   What have you done for goodness sake ?

                                        Man !  what  have you done ?

                                        Hey !  what  have  you  done ?

It  is more like  “manly” phrase. 

Yahu   bizim  çaylar  nerde  kaldı ? -à  Hey , where is our tea ?

Bu  da  ne  yahu [yav] ?  à What  an earth is this ?
