I consider my English to be fairly good, and as soon as I saw “wong“, I told myself it was either a typo for "wrong" or someone's last name. Discovering its subculture meaning was bit of an eye-opener.
But discovering the history behind wong proved to be even more fascinating. As Merriam-Webster attests, wong is an obsolete Old English word for field, and meadow
Middle English, from Old English wong, wang; akin to Old High German -wang field
If further proof was needed
WONG, WANG, a termination of local names in England,
as Basfordwong, Cornerwong, is the A.S. wang, wong, a plain, field, allied to Dan. […] Wong occurs frequently in Norfolk.

However, I suspect the majority of Anglophone speakers would be most familiar with Wong as a surname. It is said that Wong is the 3rd most common Chinese name in the US and the most common Chinese last name in Canada. However, in old Britain, it was also an English surname derived from geong meaning young.
Wong family history in England begins with Thomas Wong, married at St. Martins in the Field in Westminster, England, at the end of 1699.
Here is the Wiktionary entry

In Old Javanese, it had the following meanings
- person, human being
- people, society

It's a pity a word with such noble and humble origins has been appropriated and sullied, and its very presence banned in some gaming communities.
In conclusion, the word wong has several different meanings, mostly obsolete, but in recent years it has taken on the vulgar overtones mentioned in Green's Dictionary of Slang and in Urban Dictionary.
