Please males dont EVER use that term when adressing a female...

Mother.
[Short for mama.]
ma - informal terms for a mother

So you are calling the female by the name you would call your own mom... which to me being as I do not have kids and I am not anyways mom, it is a disrespectful term...
WHAT DOES EVERYONE ELSE THINK?
