A fledgling trope or YKTTW draft is short on examples. This term is a call for the Troperville community to rack their collective consciousness and feed the entry, so it can grow into a healthy, model trope for others to aspire to.
But this tag should also be taken with a grain of salt: Once the trope has been launched to a normal wikipage (and cross-linked and indexed), Wiki Magic alone will provide more examples over time; the YKTTW only needs enough examples to support what its definition is. If a given YKTTW already has a handful of good examples but it still Needs a Better Name or Needs a Better Description, it may be better to discuss those issues instead.
Be especially careful if the suggested examples seem to be all over the place (aka Square Peg, Round Trope), or if someone thinks a YKTTW itself is "chairs" (aka Not a Trope), because in these cases a large number of examples will not defend younote — here, you really do need to discuss and work on the definition first before you go asking for more examples.
Note that if the Needs Fictional Examples variant of this message is used, that indicates that the examples are overly concentrated on Real Life. Keep in mind that Real Life is not the main focus of TV Tropes, and if a trope page Needs More Examples, a horde of Real Life examples and none from other genres may not be what that trope needs. We are wiki for documenting tropes in fiction, and if a there are little to no examples from fiction to be found, it is probably Not a Trope.
For a list of the pages that actually need more examples, see Tropes Needing Examples.
