The TVTropes Trope Finder is where you can come to ask questions like "Do we have this one?" and "What's the trope about...?" Trying to rediscover a long lost show or other medium but need a little help? Head to Media Finder and try your luck there. Want to propose a new trope? You should be over at You Know, That Thing Where.
If it is an in-universe example you can add it to the work's trope list as long as you make it clear it is internal to the work. The words "In universe" (or the invisible [[invoked]] tag if you can't work the phrase in universe in) will make the little coloured dot turn black.
Make sure it is only used for explicitly in-universe examples though, and make your explanation really good. Also leave detailed edit reasons.

Is there a trope for in-universe things that make the fandom happy (perhaps as a result of pandering to the base)? And The Fandom Rejoiced seems deliberately limited to creator-level things, but even though it's obviously subjective, I can think of several in-show examples where a fandom (or at least an online fandom) was united in happiness (on V 2009 when Tyler died, or because of the events in a recent episode of Bones).
