Sarong Party Girl (also abbreviated to SPG) is a derogatory term
used in Singapore, and, less frequently, in Peninsular Malaysia. It
describes a local Asian woman (Chinese, Malay, Indian, etc.) who
usually dresses and behaves in a provocative manner; and
exclusively dates and prefers caucasian men. This can be considered
a variant of the Pinkerton Syndrome, as it involves an Asian woman
who only dates Caucasian men and considers them superior to their
local counterparts.
The term first achieved international notoriety after Jim Aitchison
(with illustrations by Theseus Chan) published a book entitled
"Sarong Party Girl" in 1994 that offered a satirical portrayal of
the SPG and related aspects of Singaporean culture.
The stereotypical Sarong party girl has extremely tanned skin, a
false foreign accent, and is provocatively dressed. Originally, the
outfit of choice was thought to be a bikini/tank-top paired with a
sarong. Many of them frequent clubs or nightspots that are popular
with expatriate Caucasians in order to meet and form relationships
with these men. Sarong party girls are known to prowl specific
nightspots in Singapore along Clarke Quay, Emerald Hill and City
Hall
