Qatl-e-aam is an Urdu phrase which means killing of common men (or persons really, not men as such). So any killing which is just for the purpose of killing anyone who is present at the moment and not directed at someone specific, is qatl-e-aam. However the phrase is used for praising beauty, the way one could call someone’s beauty a killer.
As for this song here, it’s a ghazal with a relatively long meter, even though it might not sound like a typical ghazal.
