Basic Trope: A character who doesn't tolerate poor grammar.
- Straight: Bob gets irritated with Chris using bad grammar.
- Exaggerated:
- An easy way to activate Bob's Unstoppable Rage is to confuse the words "your" and "you're".
- Anyone who misspells a word is considered worse than a murderer or a rapist.
- If anybody says or writes the word with improper grammar even once, Bob will destroy the world.
- Downplayed: While not nitpicky about it, Bob always corrects Chris' usage of a sentence, even when there are more important things to do.
- Justified:
- Bob is Chris' English teacher.
- Bob sees grammar as Serious Business.
- Chris is an immigrant whose first language isn't English and he must pass an English proficiency test to gain citizenship. He's making mistakes that could cost him a passing score.
- Inverted: Grammar anarchist intentionally: destroying grammar
- Subverted: "'I will eat fish for dinnor and drank milk'? It's 'I will eat fish for dinner and drank milk with my dinner.' Idiot."
- Double Subverted: "...And it should be drink milk, not drank milk."
- Parodied:
- Bob is a literal Nazi who imprisons and/or kills people for not adhering strictly to all his idiosyncratic, poorly explained, and self-contradictory interpretations of grammar.
- Chris gets strafed by an Me-262 fighter jet after missaying something.
- Zig-Zagged:
- Bob is only sensitive to grammar flaws on certain occasions.
- Bob is more sensitive to some grammar errors than others.
- Bob engages in Selective Enforcement of this: for whatever reason, he'll correct grammar mistakes made by Alice and Chris but not Cathy and Adam.
- Averted:
- Bob doesn't care whether other people use good or poor grammar.
- Everybody uses uniformly good or poor grammar, including Bob, so he's in no position to judge.
- Enforced: Bob is a character in a children's Edutainment Show, and the producers decide they want to teach children proper grammar, so they incorporate this into his character.
- Lampshaded: "This isn't grammar class 101, Bob."
- Invoked: Bob is answering questions at a press release. Chris, knowing that Bob is a grammar Nazi, intentionally words his questions with improper grammar to get a rise out of Bob, making him look petty and foolish.
- Exploited: Chris notices that Bob is obsessing over his bad grammar and amps it up to spite him.
- Defied: Bob is about to rage at Chris for using bad grammar but takes a deep breath instead, choosing to let it go.
- Discussed: "So, Bob says that bad grammar is akin to robbing someone's car. How thoughtful."
- Conversed: "Damn, that show's so uptight about grammar. 'This is good grammar,' 'that's bad grammar' ... I'll give you grammar if that's what you want so badly..."
- Played for Drama: Bob has PTSD in regards to an unfortunate event that triggers from serious bad grammar. After Chris makes too many grammatical errors, rather than simply correct him, knowing it wouldn't work, he beats the stupidity out of him. Chris has since stopped and learned from his mistakes, but Bob has to face the consequences for his Disproportionate Retribution.
- Implied: Bob is The Ghost but he has a reputation as this from other characters' comments on him.
- Deconstructed: Bob's strict policies on grammar have caused major backlash from the public.
- Reconstructed:
- People come around to Bob's way of thinking.
- Bob leaves for a society where most people already agree with him or starts his own with the help of some such people.
- Played for Laughs: The Know-Nothing Know-It-All Bob is challenged to correct a sentence in a language he doesn't speak — which is grammatically correct in the first place.
Back to Grammar Nazi to learn proper grammar, you fool!
