Insult, although not a derogatory term. Shortened form of "emak engkau hijau", which literally translates to "your mother is green". First found from a video of two Malay boys arguing in a park, with one of them proceeding to say the above phrase. Later scenes show them engaging in a fistfight.
This phrase has become the mother of all insults in the Malay-speaking world of the
Internet, although some say in the SouthEast Asian world of the
Internet as well. This phrase is
popular among Malaysian netizens when foreigners say stupid things about Malaysia or Malaysians.
