- Mr Sondheim, look, I made a hat! Where there never was a hat! It's a Latin hat at that!
- Adorkable: Dear god, the man is a ray of sunshine. He's genuinely delighted by fan content made of his work, constantly interacts with people on Twitter, and still fanboys over everyone (even though he's pretty darn famous himself).
- Added Alliterative Appeal: A staple of his work, with lines like "rebels at a revel", "a middle of a military mess", etc.
- As Himself:
Billy: Can I get tickets to Hamilton?Lin: NO!
- Cameoed in an episode of the musical dramedy Smash.
- Also made a cameo in Difficult People, confronting Billy Eichner for faking a blurb from him saying Eichner's character's play is "better than Hamilton."
- Creator Thumbprint: Themes of immigration and legacy feature prominiently in his work.
- Genre-Busting: His musicals are notable for mixing hip-hop, rap, and Latin music together with more standard showtune fare.
- Gratuitous French: In a tweet from 2013, Lin complains that Lafayette "wants" to rap in French, and that he has to go learn French. While it only pops up once in Hamilton, it comes back in Moana during Shiny, when Tamatoa inexplicably says a line in French despite being a crab from the realm of monsters located somewhere underneath the Pacific.
- Gratuitous Spanish: As seen in his acceptance speeches, Twitter feed, and In the Heights (Justified Trope, since it's a musical about the Dominican neighborhood of Washington Heights).
- Rhyming with Itself: "Philip, you would like it uptown / It's quiet uptown..."
- "Sesame Street" Cred: He's done quite a bit of work for the show, playing occasional roles and singing the theme song to Murray Has a Little Lamb.
- Sliding Scale of Idealism vs. Cynicism: His works fall fairly high on the "idealistic" half of the equation.
