For example, I have a concept in my head that's like a hashtag but would translate to "over-optimized 80s/90s technologies that have aged poorly". It's a categorization that overlaps with a sense of frustration (typically because I'm using one) and joy that I'm seeing fewer of them these days...
I have a lot of similar "feelings" that are felt instantly, but would take dense English to express. It is kind of like observing some behaviour in a large codebase and trying to remember what's causing it. Connecting all the dots to find a satisfying explanation isn't always immediate.
This write-up on "clueyness" is a similar example to what I experience from time-to-time: https://waitbutwhy.com/2016/05/clueyness-a-weird-kind-of-sad...
