(n.) vaguely pejorative Cantonese slang for foreigner. Translations differ depending on who you ask. Apparently it was once meant to mean "foreign devil" (an extreme insult), but usually these days is said to mean "ghost man" due to white foreigner's pale skin and is used as a general term to mean foreigner. Gweilos get upset about being called this. Chinese think it's no big deal.

Gweilo is Cantonese. It translates as 'Ghost Man' and is used to describe a Caucasian foreigner.

Although most of China is familiar with this word only Cantonese speakers use it as a derogative way of describing a white person.

It is considered highly offensive in Mandarin China and with some white people.
A Cant (Cantonese person): "Did Gweilo like his dessert?"

Cant waiter: "Yes he did."

White mixed European male who ate THE dessert (and knew what the word meant) remarked: "Did that Cant just call me a Gweilo???"
