We’ve all met someone who says something rude without thinking or maybe they “rub someone the wrong way” on purpose. In the USA, people often use short phrases to talk about behavior like this. These phrases, called idioms, help describe actions in a way that’s easy to understand and a little more colorful too.
Instead of saying someone is rude, Americans might say they “have no filter” or “bite someone’s head off.” These sayings come up at school, at work, even at the dinner table. They help people talk about tough behavior without being too harsh. Once you know them, you’ll start hearing them everywhere and you might even use one yourself.
