I think since editing most of the time means taking something away and the latin preposition "DE" means "reduced" or "minus" it is quite clear to name it that way. A fitting title is hard to be found anyway and it should be short to be remembered. The good thing about a "de-d" title is that you can perfectly google for it. One CBB edition is named "High Tension Minus One Edit"... googling for that really makes no sense and believe me I did that a lot, to check for reactions.
