Definition
A 'winker' can refer to an eye blink or a flashing light, depending on the context 😉. In British slang, it can also refer to the penis (use with caution!). As an eye movement, it's a quick, playful closing and opening of one eye. Unlike a regular blink (done by both eyes), a wink is a deliberate signal. As a light, it's a blinking signal often used for warnings. The meaning changes, depending on location, emphasizing the need to be clear in communication.
