Hong Kong Cantonese: Derogatory Terms For Mainlanders What derogatory terms are there for mainlanders in Hong Kong Cantonese?

I know there are a lot of terms that start with 北 but I'm not sure of specific ones.
The one with 北 could be 北姑 or 北佬. 

There are many other derogatory terms for Mainlanders, including:

强国人
皇虫, 蝗虫
