Some Snark meanings might not have been what Lewis Carroll thought of, but he left lots of space for even more meanings than you can think of. I, for example, associate growing greens with high electricity bills. Others have other ideas, which might be better.
“The Hunting of the Snark” by Lewis Carroll: It’s said of the Snark, “You may serve it with greens.” As the author is a mathematician, this means Green’s Theorem being applied as a minor step, and the Snark stands for a theorem that is fiendishly difficult to prove.
