You have a trope, and the name seems to be fine, especially if it's an established term. But it's still kind of an obscure name outside of that particular {{Fandom}}, and/or it's hard to spell. So it's not that likely to be easily searched for.

This is a major cause of TropeLaunchPad duplicates of existing tropes.

So [[Administrivia/EverythingYouWantedToKnowAboutChangingNames if a new rename isn't called for]], creating redirects for it is the next best thing. This is popularly abbreviated by saying "redirects are free" -- but it should be noted that the ability to create redirects is '''not''' a valid argument for or against renaming.
For instructions (and general guidelines) on exactly ''how'' and ''when'' to create a redirect, see Administrivia/CreatingNewRedirects. There is also [[ this]] forum thread for Needs A Redirect questions - feel free to ask!
