Recorded use
Wiktionary examplesThese source excerpts show how DS9 appears in context. They illustrate usage; the definition above remains the entry’s reference meaning.
In fact, I think one of the main reasons people write and read Treksmut (tm), is that the show very rarely shows these extremely attractive and appealing characters in romantic situations or settings, except for one-episode flings, which are usually conveniently forgotten by the next show, although this is refreshingly rare on DS9 and Voyager.
I've had hardcore Fivers point to both Jadzia Dax AND Kira as ripoffs of Ivanova (they can't decide which, I suppose) despite the fact that both premiered on DS9 first, and JMS didn't get rid of Ivanova until AFTER The Gathering, which showed when DS9 first came around.
