How about patrimortism? The thing to do is find a character in myth, legend, or literature, and coin a word therefrom: e.g., Oedipus complex, chauvinism. It might be an East-West thing. We have the aforementioned Oedipus, but also Kronos dispatching his father Ouranos, and subsequently be deposed by his son, Zeus (cf. Goya's painting of Saturn Eating His Son). In the Bible, we have Jacob supplanting his brother Esau by duping his father Isaac to bless him instead. Ah, well. I'm sure the others will come up with better suggestions. But, just one last inkhornish word: patrothanatoblepsism 'contemplation of the death of one's father'.

Ceci n'est pas un seing.
