a stub from an answer on << Gwailo >>
In 80's Hong Kong, this is a phrase a lot of sweary British sailors picked up from their Chinese shipmates (HMS Swift 1987). I was told it means
' Go fuck your mother' but then I'm not Cantonese - just another gwailo....
'hey English boy ! Dieu lay lo may ! '
' Yeah fuck you too Lee - see you Kowloon side'
