Ok, I thought Stanford was really bad with all their acronyms for frequently used words: Mem Chu, fro yo, foam, eanab...

Well here's a short list:
TST - Tsim Sha Tui, a district in Kowloon
DB - Discovery Bay, expat commune, oops I mean expat community on Lantau Island soon to be next to Disney Hong Kong in 2005-6
DPD - dai pai dong (food vendor stalls, that are illegal and probably will give you a bad tummy ache)
KCR - Kowloon-Canton Railways, gets you to the China border and New Territories
MTR - Mass Transit Railway, subway system
LKF - Lai Kwai Fong, party central of SOHO
SOHO - South of Hollywood Rd in the Mid-Levels district

There are more, just can't remember them off the top of my head. I'll probably add more just to archive :)
