Which ma belongs in the phrase 我 "ma" 好的 This may be a SE dialect thing, but plenty of my friends say 我 "ma" 好的 to mean 我很好 or "ma" 好的 to mean good or I agree with you.

Can someone tell me which character (if there is one) is supposed to be used here?
I think you mean "man" instead of "ma"?
If so, it's 蛮. 


  我蛮好的.
