Undeadline (

1. Initially appears identical to a deadline, but when you think it must have passed, staggers back up and wanders around some more, feasting on the brains of the living.

Undeadlines can return arbitrarily many times to torment the living, and can usually only be destroyed by a sufficiently powerful deliverable, although even this does not guarantee safety from sequels.

They can appear spontaneously anywhere deadlines naturally occur, but are particularly attracted to government contractors and work environments which do not have a clear-cut deliverables process in place.
