Proper English , Manglish or Broken English which one you would choose ?

assalamualaikum and hye to everybody..... 7th of july i create new post doesnt mean i'm back to the blog. no no no no. XDDD hmm. last week there's a bro from IB ( i dont know IB stand for what ) he made a research on us ( my classmates). his tesis maybe. it's about manglish. yeah malaysian english. like " bro , i busy now i call u back HA ?. later later !!!" in proper english u should talk like this "Hello  bro , i'm busy right now. i'll call u back after this." if i'm not mistaken. for me manglish is AWESOME. however , the awesomeness of manglish cant write on your essay. cant use when u talk with foreigner. ( it's not good to talk with our carca marba english) the most important. when u go to oversea.. everybody will "haaaaaaaaaaaaaa? " . is't eng from malaysia ? soooo bad. how come u flight here ?..  for me manglish and broken eng it's important for beginners. first of all. you must master your grammar. it's okay if ur vocab was soo tunggang langgang just like me. but a journey to the ROM begin with first step.. hahahah i dont know is that the exact idiom.. i'm also listed in beginners. from broken eng you improved to manglish . when you master in your manglish it's easy for u to learn proper english... it's an advise. 3 stage i on the 2nd stage. .i know talk in eng doesnt make me an american but if american talk to me , i should response in bm laa ? XXDDD
