Singapourien means Singaporean in French. It's for the pretentious high class snob in you.
That's it. And its because so many Singaporeans love French and business owners like to name their shops with pretentious french names like Le Kopi, Le Hair Salon and it makes no focking sense.
How about those people who says "excuse moi" when in fact it should be "excusez-moi?" I could go on and on about these people...
Oh an interesting fact, do you know that French Fries are not from the French?
Here's another one, Wetteeshirt are not wet. Mind blown.
All the tees are proudly made in Singapore for Singaporeans and people who love Singapore. 100% cotton and suitable for the damn hot weather so you can wear it to the padang or stadium.
