You know you're in Malaysia when:-
1) "I see you in 5 minutes" means 15, 15 means 30 and 30 means 120. Do the maths.
2) Lepakking (loitering aimlessly) is a legitimate pastime.
3) Teh tarik (type of Indian tea) kurang manis (less sugar) means only 5 tablespoons of sugar
4) The first decision that involves thinking every morning is deciding what to eat
5) Bata is synonymous with shoes
6) Petaling Street is automatically tipped as a tourist hot-spot
7) Anyone can watch English, Cantonese, Hokkien, Tamil and Hindi movies and understand it perfectly if they can understand the Malay subtitles that go with it
8) Most advertisements will have a least one Malay, Chinese and Indian to (over)emphasise racial harmony so that 'no one' feels left out. Someone clearly forgot the Iban, Bidayuh, Melanau, Bisaya, Lun Bawang, Orang Ulu, Kayan, Kadazan, Bajau, Murut, Oang Asli, Penan, Baba Nyonya, Peranakan...
9) Voices over the intercom in trains, airports and radio sound like Americans trying to speak English like a local (like Chow Yun Fatt in "Anna and the King")
10) You KNOW you are in Malaysia and have truly assimilated when...
