Kentucky Canker Sore

A sore one gets when he forgets to wipe his anus and then precedes to participate in athletic activities. The sore is generally very rashed and dirty. While the only cure being human saliva, one must physically eat his own Kentucky Canker sore out of his asshole or ask a friend/relative for assistance.

When Fred couldn't bare his "Kentucky Canker Sore" anymore he just decided to call up his buddy Tim.

Clanker Sore

The persistent mental fatigue, eye strain, and existential dread caused by spending too many consecutive hours arguing with AI models, debugging prompts, regenerating outputs, or watching agents confidently invent nonsense. The AI-era equivalent of a canker sore.

Symptoms:

* Asking “Why would you do that?” to your laptop.
* Reading the same hallucinated answer five different ways, hoping one is correct.
* Accidentally saying “Good job” after an LLM finally returns valid JSON.
* Feeling compelled to open yet another chat because this prompt will definitely work.

“I spent eight hours getting my coding agent to stop deleting the config files. I’ve got a serious clanker sore.”
