A "Sarong Party Girl". Rampant in Singapore and other areas in Asia. Usually the finer specimens of the female population but plagued with an addiction for caucasian dick. Though these women are typically not prostitutes, they do lend themselves to "loving you long time" depending on size of wallet and promises of greener pastures.
