For example: “Applesauce” is equivalent to “I can’t hear you”, or “speak up” or “stop mumbling”.
“Applesauce Factory” means “I can’t hear you because you are too far away or something noisy is making it hard to hear you” - very convenient verbal shorthand for when it’s too noisy to say all of that at once.
“Soufflé” - “I need to introvert for a while” (similar to how a soufflé needs delicacy and time to settle)
“Crockpot” - “I need to focus on work and I cannot be interrupted for anything less than an emergency” (similar to how a crockpot won’t work if you keep opening the lid over and over)
We settled on using foods because they are inherently neutral (we don’t pick foods we dislike to code for obvious reasons), and sometimes correspond to their meaning (like crockpot).
Another way to look at it is that we define functions with food codes that handle the messy, “violent” (to use TFA’s language) communication so that we understand what we are trying to convey, but at execution time we only call the function itself, not the code inside, so the language that could otherwise inadvertently hurt feelings is unspoken, even though it is still clearly expressed, but in a manner that doesn’t invoke negative reactions.
The biggest advantage of this system is that we can say things directly without accidentally hurting feelings or dancing around the topic to avoid accidentally hurting feelings. Feel free to utilize this in your own relationships. I’d never heard of anything like this before starting it and it has worked wonders for us.
