Cardie
Common language division alert from my pensioner post: a cardie is a cardigan. Specifically, it is the kind of cardigan that would be worn by an old codger.
Incidentally, according to Google, an upper-cased Cardie is:
[a] derogatory term for Cardassians used by Starfleet personnel involved in the Great Patriotic War.
Cardassians, as any fule and Wikipedia kno, are:
a spacefaring race in the fictional Star Trek universe. The Cardassian Union was introduced in the Star Trek: The Next Generation episode "The Wounded". Cardassians were one of the main parts of the storyline in Star Trek: Deep Space Nine. The Cardassian homeworld is Cardassia Prime in the Alpha Quadrant.

The Cardassians were conceived by the writers to provide an enemy race with whom the protagonists could interact, unlike the Borg where such drama is difficult due to their lack of personality and individualism.
