Tropes listed here limit all examples and wicks to In-Universe. We find that a lot of tropes are about reactions, but the reactions come from the characters or narration often enough that they become objective tropes. This means the trope is only to be listed when the reactions are from the characters or narration, never the viewers. Even if they can be Audience Reactions, the tropes here are only to be noted when the characters and show have the reaction. This also means that tropers should not Pothole or Sinkhole the trope in lines when it's not actually in the show. Compare No Real Life Examples, Please!, Character Reaction Index. Compare/Contrast YMMV.
