ethnic group, one of the Orang Asli in Malaysia, (slang) slave; unsophisticated or uncivilized person
etymology notes
Sematic extension of the derogatory/racist Malay slur, which in Malaysia means "unsophisticated; uncivilized". The shift is likely in the sense of an unsophisticated country bumpkin being easily fascinated by the "new" things and experiences they might find in a big city. See also suaku.
