Today we talk about fire . Before we continue , let's talk about two words often used to explain this idiom : rumor and gossip . Rumors and gossip are stories or pieces of information that are passed from person to person but have not been proven to be true . They are often about something bad . If the word on the street is that something is really bad , it just might be . Or if you hear unpleasant things about someone or something from many different people , there may be some truth to it . Here's an example : I think we should start looking for another job . I've heard that this bank is going under . It could just be gossip . In other words , there must be at least some truth to all the talk . The logic is this : If many people are saying that something bad is happening , it could be partly true . We say this idiom several ways . People will definitely understand your meaning . Here is another example . Hey , I hear you're going out with that new guy at work . We went for a long walk together . That's about it . Well , be careful . Rumor has it that he is bad news . What kind of bad news ? Well , he's been married before . There's no crime against having a marriage that didn't work out . But he's been married four times . My cousin knows a former wife of his . She says the guy owes money all over town . This is all just gossip . Look , I'm just saying be careful .
