That's the point of the Vivisepulture Ping List. If you don't make it to the grave at all (like the not-so-late, just cold-blooded, dragon Santana), it's semivivisepulture. If you get partially buried, it's vivisemisepulture.
The only thing left to do with this new word is to discover how to pronounce it.....it needs to be used more often, at inopportune moments etc. :)
