Explanation

  • A phrase used to preface confidential information, indicating that it should not be shared with others.
  • Between you and me: The standard form, limiting the secret to the speaker and listener.
  • Between you, me, and the lamppost (or gatepost, wall): A humorous, folksy, or emphatic extension implying extreme secrecy – so secret even an inanimate object won't 'hear' it.

Origin

  • Between you and me: Establishes the exclusive pairing for the secret.
  • The lamppost/gatepost addition is an idiomatic exaggeration dating to at least the 19th century, used for emphasis or humor. It personifies an inanimate object as a potential 'listener' that must also be excluded.

Alternatives

Slang/Informal:

  • Keep this on the DL (Down Low = secret)
  • Mum's the word (An agreement to keep quiet, often a response)
  • This is hush-hush
  • Keep it under wraps

Milder/Standard:

  • In confidence / Strictly confidential
  • Can we speak privately?
  • For your ears only (slightly dramatic/spy-like)

Situational Appropriateness

  • Between you and me is suitable for informal and semi-formal situations where confidentiality is needed.
  • Between you, me, and the lamppost is strictly informal, often humorous or slightly old-fashioned. Avoid in professional settings.
  • Use only when you genuinely trust the listener and intend secrecy.

Misunderstanding Warnings

  • Grammatically, between you and I is incorrect but sometimes heard. The fixed idiom is between you and me. Learners should stick to me.
  • The core meaning of confidentiality is usually clear.

Examples

  • Between you and me, I think John is going to propose tonight.
  • Don't repeat this, but between you and me, the project is way over budget.
  • Between you, me, and the lamppost, I wouldn't trust him with that responsibility.

Dialogue

Alice: Can I tell you something? Between you and me?

Bob: Absolutely. What's up?

Alice: I heard they might be offering voluntary redundancy packages soon.

Bob: Wow, really? Okay, I won't breathe a word.

Charlie: So, what did you *really* think of the presentation?

Denise: Well... between you, me, and the lamppost, it was pretty disorganized.

Charlie: (Whispering) Totally agree!

Social Media Examples

  • (Rarely used publicly due to the inherent contradiction).
  • DM/Private message: Hey, quick question, between you and me, did you hear anything about the team reshuffle?
  • Humorous Tweet: Between you, me, and the lamppost (and my 500 followers), I think pineapple on pizza is underrated.

Response Patterns

  • Acknowledging confidentiality: Okay, got it. / My lips are sealed. / You have my word. / It won't go any further.
  • Non-verbal cues: Leaning closer, nodding seriously.

Common Follow-up Questions/Actions

  • The speaker shares the confidential information.
  • The listener is ethically bound (in informal contexts) not to repeat it.
  • Breaking this confidence is considered a breach of trust.

Intonation
