This expression is used frequently to refer to completing a task at the last minute before a deadline. English speakers use the 12 hour clock as opposed to a 24 hour clock, so the eleventh hour is the last one to finish a project or event on a certain day. “He finally got the paper in at the eleventh hour.”
The steam engine was popularized for trains in the United States in the 1800’s. When pressure builds in one, steam has to be “blown off”, or released from the mechanism. This expression is widely used by Americans when they need to relax after being in a stressful or pressure situation: “I need to blow off some steam and go golfing.”
Native Americans would chew whale fat like gum, socially or to pass the time. 'Chew the fat' refers to sitting and talking socially about lighthearted subjects with someone. “Let’s get together and chew the fat after work.”
Turkeys are white, bumpy, and cool to the touch when dead and plucked. This expression refers to the way one looks going through withdrawal from a drug quit without assistance: cold and pallid and moist to the touch. “I quit smoking cold turkey.”
Political campaigns in the world’s oldest democracy would try to engage people to listen to a speaker and vote for a candidate with wagons of musical bands before TV and cars. If people “jumped on the bandwagon”, they were offering their support literally to that candidate that was using popularity to gain votes. This expression is used in English to refer to joining a cause or movement, especially one that is popular, or rooting for a sports team that is likely to win a championship. “I jumped on the bandwagon and tried that new diet everyone is talking about.”
This term comes from baseball. When a pitcher has good control of the game, he is “on the ball”. English speakers say they are “on the ball” when they are on top of a situation, a project, or just completing a task. “He was really on the ball and got that project done before the deadline.”
The Farmers’ Almanac was used throughout America, which was predominantly agricultural until after World War II, to predict weather conditions annually. The Almanac listed the full moon cycle. It is rare for a month to have two full moons, but if it did, the first one would be in red letters and the second in blue. Hence, the expression “once in a blue moon” means that something occurs very rarely. “My daughter eats broccoli once in a blue moon.”
Modern America was created by settlers colonizing new towns across the North American continent. Towns almost always had a church with a bell as a central meeting place. Before alarms, electricity, and phones, the bell was rung to remind townspeople of events and hours. Hence, if a clue or signal “rings a bell”, it is an alarm trigger to remember to do something or just to remember something in general. “My mom calling me rung a bell that her birthday is next week.”
