Ok, the above is obviously low key dystopic but at the same time I do love an informal or metaphorical theorem name, like the ham sandwich theorem (given any n regions in R^n, there exists an (n-1)-plane bisecting all three) or the shoes and socks lemma, i.e., (f ∘ g)^-1 = (g^-1) ∘ (f^-1).

You guys know the squeeze theorem, a.k.a. the sandwich theorem? The one where if you have 3 functions that satisfy:

g(x) <= f(x) <= h(x)

And the following is true (as x approaches a):

L = lim g(x) = lim h(x)

Then (as x approaches a):

lim f(x) = L

Well it just clicked for me that in my Eastern European country, we call it "the two policemen lemma". Imagine how much of a police state it must be, that people see a line squished between two other lines and think: "Damn, another enemy of the state..."

I can only assume this will make every line of code I write 200% cuter
