Why are the DD Girls called that?


Why are the [DD Girls](http://sailormoon.wikia.com/wiki/DD_Girls) named such?

Their name in katakana: [ディーディー・ガールズ], has no meaning, other than just being
"DD Girls"...

How do we even know that they're called the DD Girls?




The [DD Girls](http://wikimoon.org/index.php?title=DD_Girls) only appear in
the original anime; they are not in the _Sailor Moon_ manga or consequently,
_Sailor Moon Crystal_. In their first appearance in the anime (in the first
half of ep. 45), they identify themselves as the DD Girls:

> Queen Beryl: In moments, Queen Metalia will be fully resurrected. I will
> allow no one to interfere. Anyone who can finish these girls [the Sailor
> Senshi] off, step forward.
>
> DD Girls: Please let us, the DD girls, take on the task.

(For reference, the line spoken by the DD girls sounds roughly like
その役目、我がデイーデイー・ガールズに, but my Japanese skills are extremely lacking and I may
well be wrong.)

There does not appear to be an official explicit explanation for their name;
if there were, I would have expected someone to point it out already
somewhere. However, if I had to take a guess, I would suggest that it is
simply a matter of themed naming: consider that the _DD Girls_ show up when
the Sailor Senshi are at _D Point_. (They also work for the _Dark_ Kingdom,
but the correspondence between the letters is less overt there, so that seems
less likely.)
