The mystery of the embouchure

The other evening we had Ukrainian visitors to dinner. The youngest of them, AK, spotted my trumpet, flugelhorn and trombone in the music room. We got chatting about them. He has spent most of his 28 years in the UK and speaks pretty much native English. After a couple of minutes of chat, he asked me the inevitable question.

Not: "Does it annoy the neighbours?".

Nor: "Does it annoy your wife?"

Nor: "Can you play [whatever]?"

Nor even: "Can I have a go?" (that's usually much younger visitors).

No. He asked whether it's hard to do the embouchure. And at that moment it struck me that everybody seems to know about embouchure. Whenever the subject of trumpet comes up with friends and new acquaintances I can virtually guarantee that they will say sometime about embouchure.

How come? It's not as if playing wind instruments is a common feature of our culture, or a regular subject of normal conversation. And the word embouchure itself is a bit of a mouthful, so to speak.

So how come so many people know the word and know roughly what it means?

Are there similar "iconic" technical terms associated with other musical instruments? (In the music room we also have guitars, a piano and a cello, but none has prompted any visitor to use an "iconic" technical term yet.)
