troper

One who tropes.

A book of tropes (phrases or verses added to the Mass when sung by a choir).

A contributor to the wiki website TV Tropes.

Since its [TV Tropes’] founding in 2004, more than 42,000 people have volunteered to be “tropers” like Barbara—a mixture of fans, writers, educators and amateur academics smitten by pop culture and accessing their inner Joseph Campbell. […] There’s a section called “Troper Tales,” about the ways tropes have shown up in the tropers’ real lives. […] He [Fast Eddie] thought up the site [TV Tropes] during a discussion on Buffistas.org, a community of “Buffy the Vampire Slayer” enthusiasts, a group of whom became the first tropers.

Thus, TV Tropes was born, an online encyclopaedia, which allows open collaboration among its contributors (the “tropers”): anyone can add pages, and edit or delete existing ones. Registration is needed for access, but it is free and instant. […] On the site, each trope and each work has its own page: these contain a short description and a list of examples, often with comments and explanations from tropers.

Alternative letter-case form of troper (“a contributor to the wiki website TV Tropes”).

As for TV Tropes, I would need to be more familiar with them to identify them in a film. However, I imagine that it's a lot of fun to watch a movie with other Tropers and be calling them out as you identify them. "Loser Protagonist!" "Running Gag!"

This Troper finds himself using Gintama “Zura ja nai, Katsurada!” as a swear, does this also count as a Gosh Darn It to Heck?
