Phantom's Secret Diary is a Yaoi, Slice of Life story that premiered to little affair that was written by Anthiens, aka Anthiena. Danny, now in college, relates his life through a diary that didn't actually start that way.
Contains examples of:
- Alas, Poor Villain: Danny does have sympathy for Vlad, in spite of what he's done.
- Bawdy Song: Barnacle Bill, which is a real-life song written in the 17th Century.
- Berserk Button: Don't mention the Twelfth Night party debut to Danny, just don't.
- Black Comedy Rape: Invoked/hinted at. Danny's debut at the Twelfth Night party-there's a rule about any ghost showing up alone "honoring" any who ask.
- Continuity Drift: Used to make better sense of the canon timeline, which is understandable.
- Dame Not Appearing In This Fic: Danielle.
- Depraved Bisexual: Spectra and most likely Phantom.
- Did Not Get the Girl: Sam and Danny broke up ages ago, as did him and Valerie for unspecified reasons.
- Drunken Song: As done by Vlad, Skulker, Spectra and Psyche, only Spectra is a lot less drunk. Psyche and Vlad on the other hand are completely trashed.
- Drinking Contest: A yearly one between Vlad and Skulker. Vlad always loses - probably because Skulker cheats.
- Fan Disservice: The first chapter was originally intended as a Take That! against Pitch Pearl, which is portrayed as terribly awkward.
- Flanderization: Jazz, who is shown as manipulative, but played for laughs.
- I Do Not Own: Every chapter so far. Also proclaims that the creator wouldn't like the fan fic, which is true enough.
- In Vino Veritas: Danny, who is quite a friendly drunk and Vlad, who goes between dancing on tables and being paranoid. Danny prefers the table dancing, but not for the reason you're thinking.
- Ironic Episode Title: Phantom's Secret Diary is actually written while Fenton as opposed to that other Phantom.
- Karma Houdini: Vlad. Somewhat justified: "...let's get real here: what jail is going to hold a person who can walk through walls, let alone all the other things a hybrid can do?"
- Kissing Under the Influence: Danny asked Ghost Writer out on a date while drunk. Also, Psyche and Spectra, which Danny notes would never happen when she's sober.
- Lamp Shading: A few times. The story has several potshots aimed at Danny Phantom fandom.
- Non-Indicative First Episode: The first chapter is porn. Believe it or not, it was censored/abridged.
- Noodle Incident: Invoked in Danny's first Twelfth Night party but somewhat averted, as it just about states what happened, but leaves out who asked.
- Put on a Bus: Danielle, who Danny has very little contact with.
- Slap-Slap-Kiss: Sort of. Danny distracted Spectra once by feeling her up and she slapped him for it, though she was rather flattered.
- Those Two Guys: Invoked with Vlad and Skulker, who are friends in this fic.
- 20 Minutes into the Future: Danny is now 23, going on 24. There is significance to that.
- The Unreveal: How Spectra and Psyche know each other, Danny's new boyfriend (at first) and his first crush's identity.
- Where the Hell Is Springfield?: Danny and Jazz go to different colleges in the same state, but what state is never discussed. Also Amity Park, which is stated to be on the west coast, but not what exact region.
- Yaoi Fan Girl: Jazz, who begs for details on Danny's boyfriends.
- Year X: The years in which PSD take place are obscured, being referred to as Year 0 on.According to the creator's fanon, Danny was born in 1990, making Year 0 actually 2013.
