I don't think is a widely known word, and that dictionary definition is probably irrelevant.
But literally means "perish" and literally means "day/date", so it could mean "the date of death." I found this page which includes this phrase:
> ****
That part looks almost like a paranoid poem, but "I don't remember (my?) birth nor (my?) death" seems to make sense to me.
"Unlucky" is not the primary meaning of . Some compounds like have such a nuance, though.
