When a nechrophiliac becomes aroused but has no dead bodies to make love with then they may go through the process of decreasing the temperature of their hand by sticking it in the freezer/ holding it in ice or frozen peas/ standing outside in Wick in January and having a snowball fight without gloves. Following this they have a thorough masturbation session with the freezing cold hand(s) to give them the sensation of a dead hand pleasuring them in their favourite sick, twisted perversion.
"Aw man! After watching back to back horror movies on my week off from working at the morgue I'm pure ganting on a nechrowank! Just as well I spent £15 on icepoles at asda last night. Back of the net."
