Dog-Fuck (DF) noun | verb | aviation / military slang Definition: Innate common sense. The kind of baseline understanding you’re expected to already have without being taught. If you need it explained, you probably don’t have it. Derived from the idea that nobody teaches a dog how to fuck — it just knows. Often used by instructors or senior aircrew to signal that a question or mistake should have been resolved through basic reasoning rather than instruction, checklists, or instruments. Common misconception: “DF” is frequently misunderstood by students as Direction Finding (ADF/navigation). In context, it actually means use your common sense, not your radios.
