Combination of necrophilia and milf, a mother you'd like to have sex with who is dead. For frequent users of "your mom" or "that's what she said" often you'll find your subject is a dead mother. While some may object and say this is a bastardization of the Greek roots, I'd like to remind you that language is not something we can control, it is merely something we can observe.
That "your mom" joke implies you'd like to sleep with my mother, who is dead, which would be necromilfia--gross.
