A 'cooler' is a device or container used to keep things cold. 🧊 It can be a small portable box for drinks or a large industrial unit for refrigerating food. The main purpose is to maintain a lower temperature than the surrounding environment. It works by insulating the contents and often using ice or a cooling element. 'Cooler' can also refer to someone who is calm under pressure. It's all about keeping things chilled, literally or figuratively. 😎
