What Does "BUCK" Mean? The Complete Buck Definition
The meaning of BUCK is broad, but the BUCK definition most commonly refers to a male deer. In everyday English, however, what does BUCK mean can change depending on context: it can also mean a male goat, rabbit, or similar animal; a dollar or dollar bill in informal slang; or the verb “to buck,” meaning to resist, jerk, or leap violently. As a noun, it’s usually concrete; as a verb, it often describes opposition or sudden movement.
The word BUCK used in English has old Germanic roots. Its BUCK origin is traced to Old English and related Germanic forms referring to a male deer or goat, which is why the animal sense is the oldest and most established. In modern usage, the most dictionary-verifiable BUCK meaning still centers on animals and the action verb, while slang money usage remains common in casual speech.
