Bahasa is a surely much more efficient language than bahasa indonesia. I got this from benablog and he get this from a twitter account @TussyHapsary :D Her sentences are totally funny and hurt my stomach. I think she's totally right about this. Contoh-contohnya:
English : would you mind to validate your previous statement?
Bahasa : SUMPE LO?
English : sorry, I think you miscalculated your own capabilities to handle the task at hand.
Bahasa : nenek lu kiper!
English : would you care to elaborate on that statement?
Bahasa : maksud loo?
English : there's a 75% chance I won't make it, I'm far too busy for ur stupid event.
Bahasa : InsyaAllah gue dateng
English : the meeting will start at 9:15 AM. Please be there 15 minutes beforehand.
Bahasa : rapatnya jam 8
English : please stop by our outlet. There might be stuff you'll find interesting.
