I think I agree with Helen, the shiver is going to be almost as rare as the eureka.
So I would like to lower the threshold. There have been moments on this forum when the added word(s) have clicked with me. Ah, so!
There was MikeL's Two Rivers (wind shear):

AK's first alpenglow picture when someone said 'always look behind you':

Possibly Anita's video of the Helm Bar (though at the moment I cant remember the word(s)):

(The word was fohn).
P.S. Helen, Breath is a really lovely work. And the following para, Speigel im Spiegel - I heard that very recently, by my favourite Arvo Part. (For those who dont know it, it is rather minimalistic with three repetitive notes gently but surprisingly varying).
