Trope clarification?

[soulexmod]

Hey, all -- it's come to my attention that there's a confusingly-worded trope in the tag set that I let slip through. If you either nominated or are requesting the trope "Saying Their Soulmate's Last Words", could you please clarify what you mean by this trope?

(On that token, if you're not sure what a trope means, I highly recommend you do not offer it. There are many other wonderful tropes in this tag set!)
