"overstand" is a great word and has many potential uses
As proposed by alex norris of webcomic name:

transcription of the linked comic, for the screen readers
Three-pane comic titled "learning", from "webcomic name" (alex norris):
- Pink blob is sitting in a pile of books. Their face is obscured by the book they are currently reading, and only their oversized head is visible, implying a huge brain. Orange blob smiles and says: "you must understand the world so well".
- Pink blob puts away the book, revealing their expressionless face with hollow eyes (idk how to put it, but pink blob looks like they've seen some shit). Pink blob replies: "the more I learn, the more confusing and complex everything is to me". Orange blob is no longer smiling.
- Pink blob starts emitting smoke, raises their arms in despair, and their face turns ever so slightly angry, as they say: "I overstand". Orange blob: "oh no".
Examples:
- someone who "overstands Unicode" will be unable to answer a question like "how do I count the number of characters in a string"
- I "overstand CDs" ever since I figured out how to create a complete disc image of a CD-RW on Linux
- the Myst community "overstands Myst lore": when you ask an innocent question about the red and blue books, you'll get 25 replies citing something a developer once said in the 90s on a defunct mailing list
... I'm actually having a hard time coming up with good examples, because most of the ones I can think of are complicated or obscure enough that I can't explain them in one sentence 🙃
