Mak Lampir is a witch figure from Indonesian popular culture, widely known through the television and film adaptations of Misteri Gunung Merapi that began in the late 1980s. Played most famously by Farida Pasha, the character became defined by her wild appearance and piercing evil laugh. Clips of that laugh later circulated online as a standalone sound effect, detached from the original scenes. Indonesian creators in particular reuse it for horror memes and prank videos, and its recognisable cackle now works as shorthand for a classic local villain arriving.
