Hmm. Dun think this is typical. Sounds like the dude got a filthy rich daddy... I know a friend, and his group of super rich sh_t talk a lot........ Rich kids (all the way up to 40 years old+) language is insane..... U'd go crazy hearing the type of stuff they talk about....
Play lang-mos, 包場 party Dom 任飲, 6 figure HKD birthday parties, etc. The conversation quoted above isn't unimaginable... But definately don't think is typical for 90+ in general...
