Indonesian slang

Indonesian slang vernacular (Indonesian: bahasa gaul, Betawi: basa gaul), or 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. Despite its direct origins, Indonesian slang often differs quite significantly in both vocabulary and grammatical structure from the most standard form of Indonesia's national language. These expressions are neither standardized nor taught in any formal establishments, but rather function in daily discourse, usually in informal settings. Several dictionaries of bahasa gaul has been published. Indonesian speakers regularly mix several regional slangs in their conversations regardless of origin, but depending on the audience and the familiarity level with the listeners.
