The act of making love to a long lost love or spouse after they have died. Possibly in a scenic setting like in front of a fireplace or at a grave yard. This is not to be confused with necrophilia because it embodies the love that one may have once had for said corpse.
Walter: Where were you last night Howard?

Howard: I was just really depressed thinking about Emma's passing, i had to go down to the cemetary and have her one last time...

Walter: Sometimes rigor-coitus is the only way to relive the passion you once had, I'm sorry Howard, one day soon you'll be able to join her again...

Howard: Yea, i was thinking next tuesday possibly.
