A Cantonese (Chinese) word for a person or persons of Caucasian descent. In the past, it was meant as a demeaning racial slang towards people of white decent. However; over time it has lost its meaning and is no longer meant as a degrading word. It is now used freely and carries no derogatory meanings.

The more politically correct term is bakyen which means white people/person. However, this term is not as prevalent as guailo. Another common version of this term is bakguai which means "white demon"; which too no longer carries a derogatory meaning.

The literal meaning of "guailo" means "demon guy", "ghost guy".

Alternate Spellings: guilo, guilou, guailou
