Shiny

Things that are Shiny are good things. Things can be literally shiny (in which case easily distracted people (*cough* Agents *cough*) are attracted to them) or metaphorically shiny. Indeed, in the Fireflyverse, 'shiny' is an exclamation used to mean 'cool' or 'awesome', or can be used in place of the word 'fine'; i.e. 'Everything's shiny, Captain, not to worry.' (Kaylee).

We like shiny things, yes we do, precious.
