So I just read the other thread about the K language[1] and how it's so-very-concise syntax made the author feel certain ways.

But that has nothing on this! From page 70 of the International Code of Signals[2], we find that PG 2 means, "I am dazzled by your searchlight. Extinguish it or lift it."

Not bad, but what if you reply with "AX 1"? Lots going on there! "Shall I train my searchlight nearly vertical on a cloud, intermittently if possible, and, if your aircraft is seen, deflect the beam upwind and on the water to facilitate your landing?"

I have a copy of the International Maritime Organisation (IMO) Code of Signals on my bookshelf.

3 letter medical flag codes include:

MKH Foreskin will not go back to normal position

MKI Patient has swelling of the testicles

MLF Patient has Delirium Tremens

It's a comprehensive book to say the least!

Fun fact based on the bottom panel: the peace sign (inverted y) is based on the flag semaphore signs for N and D, originally standing for Nuclear Disarmament.

This is from 100 Rabbits. Great job!!

One of my favorite flag signals is, “Nothing can be done until high tide.”

This seems like a great system, but in many years of sailing I've never encountered it actually used. For the most part is only possible to be used by large commercial vessels, but those vessels already have a dozen other redundant communication systems that are clearer and faster. Operators of small private vessels aren't likely to even know this system exists, not alone carry all of these flags, a code book, and a system for hoisting flags.
