Indonesian slang
Indonesian slang vernacular (Indonesian: bahasa gaul, Betawi: basa gaul), also known as Jakarta colloquial speech (Indonesian: bahasa informal, bahasa sehari-hari), is a term that subsumes various urban vernacular and non-standard styles of expression used throughout Indonesia that are not necessarily mutually intelligible. Regional slang from the capital of Jakarta, based on Betawi language, is however heavily exposed and promoted in national media, and considered the de facto Indonesian slang.
