**Controversy's OK on a blog; not on an encyclopedia page.  Your new revised, "improved" and seriously lengthened definition is heading towards a full article, not a one-line definition; other bits that, since you're at it, could be amended in your new version could be, for instance, "often used resentfully to reference the new-comers who had invented the name to brag about their takeover of the city" and the last bit is more like "who often had sufficient wealth to buy houses for cash, drastically increasing real-estate prices in the city and thereby disenfranchising people not able to afford HK-style housing prices, thereby generating resentment against the newcomers"  It's either a full article, a one-liner as simple as "since the HK inmigration of the late 1980s, in reference to the new Chinese flavour of the city", or no mention of it at all.  I'd rather the last one not be an option; so if there's a definition it has to be as neutral as possible (or SUCCESS will be all over us)
