Slang is a type of informal language that often evolves quickly and varies by region, culture, or social group. It includes words and phrases that may not be found in standard dictionaries but are widely understood within specific communities. Slang can express identity, create a sense of belonging, or convey humor. People use slang in everyday conversations, especially among friends or peers. For example, terms like lit or fam have become popular in recent years. While slang can enhance communication, it may also lead to misunderstandings when used with those unfamiliar with the terms.
