Recently there has been some trends in the way people speak. Like some people (May Teng for example) like to imitate the Taiwanese style or some others copying the Korean style or even the China style. They will add in those lingos which are uncommon in Singapore when they speak.
There is nothing wrong with using other people's lingo, I am not saying that there is anything wrong with it.
I have lots of overseas friends and it's true that sometimes I imitate the way they speak when I speak with them. Just for fun lol.. There was a period of time where I like to imitate the french accent. Example, they will speak like 'Zis is ze place. Zey are not ere yet.' (this is the place, they are not here yet, in french, there is not 'H' sound)
Of cuz I don't do this to my other friends, they will think I am nuts.
Actually, I sort of like the way singaporeans speak singlish. Now that we have so many foreigners in Sg, we must have some sort of 'Speak Singlish' campaign too. To prevent this unique language from extinction. With the influence of foreigners, like some of my friends who are picking up foreign accents, our own singlish will disappear soon!! Zis is not good!
So I think besides promoting Chinese and English, we should promote Singlish too.
Save our 'wah lao eah,' 'sibeh sian' or 'pek cek'.... We encourage Singaporeans to say 'wah lau eah' at least once a day! lol...
