In mechanical engineering, a crank refers to an arm attached at right angles to a rotating shaft by which circular motion is imparted to or received from the shaft, or by which reciprocal motion is converted to rotary motion. In a broader colloquial sense, the term "crank" can also refer to an eccentric person who holds stubbornly unorthodox or eccentric opinions, particularly those concerning obscure or bizarre conspiracy theories. Furthermore, in informal slang, it can describe someone who is irritable, grumpy, or bad-tempered, or it can refer to illicit substances such as methamphetamine, depending heavily on the specific context in which the word is being used within conversation.
