Someone who is instructed to keep a watchful eye for popo and intruders, while someone or a group engages in illicit activity. Whenever a lookout spots popo or intruders they are required to warn others verbally or physically. Lookouts will typically engage in ordinary behavoir, such as pretending to talk on a cell phone or smoke a cigarette to appear to be occupied and allow them to be watchful at the same time.

There may also be another lookout from a distance watching the main lookout in the case that body gesture or hand movements are used as a warning. This method is preferred in a noisy environment where a verbal signal may not be picked up.

Made famous by the late Ronnie James Dio of Rainbow, Black Sabbath, Heaven and Hell and Dio. Dio would often shout at the top of his lungs in parts of a song "Look out!". Best used in context with a loud raspy voice while flashing the horns. Most commonly heard when describing an impending situation or event loosely connected to Heavy Metal.
"Look out" is also a phrase used in tribute to Dio, often yelled by rockers before they down a shot, take a drink or on hearing the opening riff of a Dio song.
