Rubber Ducking
Noun · Hacker Culture
Definitions
The practice of explaining a bug, design, or code path out loud, often to a rubber duck or other inanimate listener, in order to expose hidden assumptions and find the real issue. It works by forcing explicit reasoning instead of vague intuition.
In plain English: Talking through a technical problem out loud to help yourself find the answer.
Example: "I solved it while rubber ducking the auth flow line by line."
