Anyway, donch argue until peng lah. Got better things to do.
Why you all still talking cock.
Chio kah peng means "laugh until upside down"nothing to do with Malay pengsan.
Anyway, maybe you can tell us what "peng" is if it's not "pengsan." The only other "pengs" I know are:
soldier - as in hokkien pengice - as in teh peng
Kam sia!
