kocak

Kocak is a term most commonly used in Indonesian slang to describe something funny or entertaining. It functions as an adjective, as in video ini kocak (this video is funny), and can be intensified with phrases like kocak banget or kocak parah. In online and social contexts, Kocak can also be used as an interjection to express amusement: "Kocak!" The expression is widespread in casual conversation, memes, streaming culture, and other user-generated content, making it a recognizable element of contemporary Indonesian internet language.

The origin of the word is uncertain; it seems to have emerged within Indonesian colloquial speech and online culture and has gained traction in the 2010s. Its usage can vary by region and speaker, and the term is considered informal and slang rather than standard Indonesian.

Beyond its Indonesian usage, Kocak can appear as a surname in some language communities; in Turkish, a cognate surname is Koçak, which is usually spelled with a "ç." When anglicized without diacritics, some instances appear as Kocak. As a surname, it carries no universal meaning across languages and is treated as a family name.
