Commonly found variants; note these may range from acceptable alternatives to non-standard forms or incorrect spellings*.
* Singlish is a largely spoken creole, and as such descriptivism (recording forms that reflect actual pronunciation in spoken language, or as appearing in the linguistic corpus) is more pertinent than strict prescriptivism. Nevertheless, the use of more standard forms (or for words originating in languages with Latin script, such as Malay, accurate to the original spelling) is recommended and encouraged.

adjective

  1. sloppy; tattered; old and unfashionable
  2. moldy; overgrown with mildew; stale
  3. Then, her job done, she left wishing all and sundry A Merry Chirstmas. It wasn't so merry because my box turned out to be chocolates. Only, they were mouldy and some five million ants were living in the caramel centre of one of them ... Exchanging notes with other recepients later, I found I wasn't the only one with ants in my proverbial stocking. And a blapok Christmas to her from all of us.
