Tropes used in Cedar Rapids include:

Actor Allusion: Ronald mentions being a huge fan of "the HBO program The Wire". His actor, Isiah Whitlock Jr., played Clay Davis on the show.
Adorkable: Tim and Ronald.
Black and Nerdy: Ronald
Break the Cutie: When Tim finds out that Roger Lemke, his idol, was a sexual deviant that even Joan couldn't keep up with and that he bribed the ASMI president for each of his Two-Diamond awards. Tim also has to do the same to save his company. He redeems himself later on.
Celebrity Paradox: The above re: Ronald and The Wire.
Chekhov's Gun: Ronald made mention that he's a huge fan of The Wire. This actually becomes useful later on.

Hot Mom: Joan
Hot Teacher: Marcy was Tim's former teacher.
Intergenerational Friendship: Tim and Bree develop the beginnings of one of these.

Ms. Fanservice: Joan.
Sir Swearsalot: Dean.
Television Geography: Due to an Iowa Film Tax Credit scandal, the movie, rather infamously, was filmed in Ann Arbor, Michigan instead of the titular city, although shots of the actual Cedar Rapids were super imposed into some shots and seen through a plane window.
Wide-Eyed Idealist: Guess.
