Indonesian slang is predominantly used in everyday conversation, social milieus, among popular media and, to a certain extent, in teen publications or pop culture magazines. For those living in more urbanized regions of Indonesia, Indonesian slang language often functions as the primary language medium for communication in daily life. While it would be unusual to communicate orally with people on a casual basis with very formal Indonesian, the use of proper or 'good and correct' Indonesian (""bahasa Indonesia yang baik dan benar"") is abundant in the media, government bodies, schools, universities, workplaces, amongst some members of the Indonesian upper-class or nobility and also in many other more formal situations.
