What does it mean????

[G-Man]

please tell me in english what "gui muy" means
(I think it's cantonese and probably not the right spelling)
The term was used in describing a girl but not sure of the connotation.
thanks,

"gui muy" may be "gwai mui",in chinese is 擛澆此.
cantonese always call a foreign (caucasian) girl gwai mui in dialogue, while a foreign boy-- gwai jai擛潔
