The phrase "word on the street" is an idiomatic expression that means the general opinion or belief held by people in a particular place, often referring to rumors or gossip. It can also refer to popular opinions or attitudes towards something or someone, based on what people are talking about in informal settings such as bars, cafes, or other public places. The phrase is used to convey the idea that the information being shared may not be accurate or reliable, but it reflects the perception of a particular group of people at a given time.
