Sum This Up in One Trope

Some works are really complex. Trying to explain them is like trying to tell the sky stop raining purple droplets of sugar-coated chocolate pieces go very nicely when you crush them through a toothpaste tube.

Then, there are these. A work with a single trope so central to it, that when said trope is mentioned, the work is the first thing that comes to mind. Enjoy!

Note: Very often, these will be Trope Codifiers or Trope Namers.

Compare X Meets Y.
