- A subtle signal or hint is sufficient for someone who is already aware or expecting it.
- The addition (to a blind horse) is often humorous or ironic, implying either that the signal is obvious enough for anyone *except* someone completely oblivious, or conversely, that even a clear signal is useless if the recipient cannot perceive or understand it. The core meaning focuses on the sufficiency of a minimal cue for the *intended*, receptive audience.
Explanation
Origin
- The phrase likely stems from the idea that people who share an understanding or conspiracy need only the slightest gesture (a nod or a wink) to communicate.
- These are non-verbal cues requiring minimal effort but conveying significant meaning between those 'in the know'.
- The blind horse part is a later, folksy addition emphasizing the pointlessness of signals to those unable to receive them, adding a layer of colourful exaggeration.

Common Follow-up Questions/Actions
- The conversation usually moves on, as the expression signifies that understanding has been achieved or expected.
- Someone might ask for clarification if they *didn't* understand the implied signal: Wait, what was the nod for?
- The person giving the signal might proceed with the intended action.
Conversation Starter

Intonation
- Generally spoken matter-of-factly.
- Stress often falls on NOD, GOOD, and WINK.
- If the blind horse part is added, it might be said with a slightly more drawn-out or wry tone, stressing BLIND HORSE.
- Example: A NOD is as GOOD as a WINK.
