It is a Cantonese word refers to "fucking retard Chinese especially those from the north of China." It sounds like "lau." There are a couple of other Cantonese words you can use with this word to specify what kind of people they are. For examples, "撈閪" and "撈B" means you north Chigger cunt; "撈仔" means dumbass awkward boys from wild north.
The 撈B homeless people have captured the streets and trees in Guangzhou. Us Cantonese decided to use nu-weapon solve this 撈blem.
