The term "bitter" often describes a strong, sharp taste that can be unpleasant. Foods like dark chocolate or coffee can have a bitter flavor, which some people enjoy, while others find it off-putting. This taste is one of the five basic tastes, alongside sweet, sour, salty, and umami. In a different context, "bitter" can also refer to feelings of resentment or disappointment. For example, someone might feel bitter after losing a competition or experiencing a breakup. This emotional bitterness can linger and affect relationships, making it important to address and process these feelings for personal well-being.
