Words and Phrases Only Singers Would Get

Some might say that singers may view the world different than the rest of us so-called 'normal-folk'--in order to find that inner place to hit those right notes. Though the meaning of certain words may be a little a different for them too.
For example, the word 'tea': what it usually means: A warm drink made from the leaves of a tea plant.
But for singers it's the liquid that's a substitute for blood.
Or take the word, harmony.
