1. “Add ‘lah’ to the end of every sentence to speak Singlish”
Singaporeans are pretty proud of their pidgin-speak so you are sadly mistaken if you think that awkwardly placing a random syllable at the end of your sentences is enough to pass you off as a local. Just changing the intonation and the stresses of ‘lah’ is enough to change the meaning of the sentence — that’s how efficient Singlish is. There are rules and nuances to Singlish, and while we appreciate your effort to blend in with the locals by ‘speaking their slang,’ nothing annoys Singaporeans more than poorly deployed Singlish, so just don’t.
