[1] One pattern of word formation modifies standard Indonesian roots (normally composed of two syllables) to have e as the first vowel and ong closing the second syllable—hence providing regular assonance with the standard Indonesian word bencong [ˈbɛntʃɔŋ], a male homosexual, trans woman, or male crossdresser.
Bahasa Binan also uses a range of standard Indonesian words with altered meaning.
The standard word for "cat", kucing, is used in Bahasa Binan to denote a male prostitute.
Another word with wide currency in Bahasa Binan, but actually typical of standard Indonesian informal word formation, is waria from wanita (woman) + pria (man), meaning "transvestite".
