Lingo refers to a specific type of language or jargon used by a particular group of people. It often includes unique words, phrases, or expressions that may not be easily understood by outsiders. For example, the tech industry has its own lingo, filled with terms like "bug," "cloud computing," and "API." Different communities, such as teenagers, gamers, or professionals in various fields, develop their own lingo to communicate more effectively among themselves. This specialized language can help create a sense of belonging and identity within the group, while also making it challenging for those unfamiliar with the terms to understand the conversation.
