When you are aroused by the picture of a missing teenager on the news or a mother of two who never made it home from wherever, and discovered in a pipe weeks later.
The media churns out random pictures lifted from her facebook or myspace page and, because she is attractive you can't help wishing you could have fucked her when she was alive.
So you drop her into your wank bank.
"Hey, you seen that missing girl on the news? I beat off to the press confrence last night." I have a serious grief crush.
'My mate is a real sick guy. I asked him if he'd seen the newspaper story of the missing women they found beaten and mutilated?' He told me he had a grief crush he couldn't shake and wished, he'd found the body!'
