Silemiyorsan karalayacaksın yeğen
If you can´t delete you will slander nephew
karalamak has some other meanings so don´t know if this is the right one - see if another fits better - http://www.tureng.com/search/karalamak
Yeğen can be ´niece´ or ´nephew´
Might be ´cross out´ - If you can´t delete it, cross it out - ?
I think cross out fits better here.
And this is taken from today´s popular series "ezel". there is this guy, everyone calls him "dayı (uncle)" and in turn he says people "yeğen (nephew)"
