Words that are missing from the English language part II

I've noticed that a lot of these thoughts occur to me when I'm in the shower. I don't know what it is about my cleansing ritual, but I suspect that it's the sensation of the warm water and the state of relaxation that it brings that focuses thoughts and opens the mind's eye. It could also be down to just having five minutes where I'm not distracted by anything more taxing than operating a shower brush and so my mind is free to wander. Archimedes' "Eureka" moment was said to have happened in a bath. I think we might be onto something here.

The French have a lovely phrase "l'esprit d'escalier" - which literally translates as "staircase wit". It's a phrase that refers to that belated moment of inspiration that strikes as you wander down the stairs leaving a party - be it coming up with a pithy retort to an insult or a witty reply to a question. The Germans have the same phrase - "Treppenwitz". I think we need a similar phrase in English for the moment of brilliance that takes you as you scrub your back - I suggest "bathroom clarity", but feel free to make alternative suggestions.

Actually, sitting down with a cup of tea has much the same effect on me (and I suspect, most English people) - perhaps "teapot clarity" would be just as appropriate.
