"It takes a lot of brass to play all those trombones in a dorm at 3:00 AM." Double entendre, no euphemism.
Isn't brass a euphemism for something else, such as "It takes a lot of balls..." But you replace it with 'brass' as to not offend, which is what euphemisms are.
Nope. It's brass as in brazen (made of brass), hard, resistant. Much older than "a lot of balls." It's analogy, but it isn't euphemism.
LoL I believe certain balls precede Brass by a long shot. -_-
Also I am floored by the quality of input from all of you, I'm glad I brought my question here. I believe I will cede my position on this matter after reading you're replies, but not entirely though.
I feel there is something in my belief which still stands true, I might not be making my point across as well as I'd like though since a few replies do sort of mention the similarity I believe exists but I believe Avy said it best
"Why is a raven like a desk?"
Why indeed...
