You are correct, it's the attestation, not an actual saying. I just think it's wild how many words were shoved together to make this abomination of a word.
It's called a composite word. English has them too, like schoolbus, but German just went crazy with them. Feels like every other word is a composite
Flugzeug = flying stuff = plane
Glühbirne = glowing pear = light bulb
But some examples just take it on a whole other level. Like "Rindfleischetikettierungsüberwachungsaufgabenübertragungsgesetz", meaning "Beef labeling supervision duties delegation law".
TBF English has words like “backpack”, which then get turned into a verb like “to go backpacking”.
But in some Germanic language like German (Dutch too), you should write all words that describe one noun together as one, which leads to words like huttentuttententoonstelling.
It's a thing in Hesse, too ;) you can also say "Ist mir Schnuppe" or "Ist mir schnurz", which essentially mean the same thing ("I don't care") but the literal translation is different. "Schnuppe" is the burnt end if a candle wick, but I have seriously no idea what "schnurz" is supposed to be, lol.
