A hyena is a kind of animal that looks like a dog with stripes. They are found in Africa and some parts of Asia. Hyenas are known for being scavengers and often eat the leftover food of other animals. In English, we might use the word "hyena" to describe someone who is selfish or greedy, like they are always trying to take advantage of others. For example, "He was acting like a hyena, trying to get all the credit for the project."
