What is described as an expression that is often short-lived and identified with a specific group?

The term that is described as an expression that is often short-lived and associated with a specific group is slang. Slang consists of informal words and expressions that are typically used within particular communities or subcultures. These expressions often evolve quickly, reflecting the dynamic nature of language and social trends.

Slang is commonly utilized among groups such as teenagers, specific professional fields, or interest-based communities, allowing members to communicate more succinctly and create a sense of identity and belonging. Because slang often emerges from cultural contexts and can fade as quickly as it appears, it is considered transient.

In contrast, euphemisms are terms or phrases used to express something in a more mild or less direct way, often to avoid offense. Jargon describes specialized terminology used in specific industries or professions that may not be easily understood by outsiders, but it tends to have a more enduring presence in language compared to slang. Abstract words refer to concepts that are not tangible, making them fundamentally different from slang in terms of their characteristics and usage.
