In Thailand, the local word for a water monitor, hia (เหี้ย), is used as an insulting word for bad and evil things, including bad persons. The word is also thought to bring bad luck, so some people prefer to call the animals 'silver-and-gold' (ตัวเงินตัวทอง) to avoid the jinx.[citation needed] The origin of this offensive meaning can be traced back to a time when more people lived in rural areas in close proximity to monitor lizards. Traditionally, Thai villagers lived in two-story houses; the top floor was for living, while the ground floor was designed to be a space for domestic animals such as pigs, chickens, and dogs.
