the difference between the words Mom & Mommy

[natalielynn]

"Terms such as "Daddy" or "Mommy" are allowed and do not break any rules. These terms are used in various sexual situations and do not imply incest on their own."

I'm not a native english speaker....
In my native language we don't call someone mommy or daddy. For me mommy\daddy have exactly the same meaning of mom and dad.
Since SM sent this mail to every performer I would like to be sure of not breaking any rules.
Is the word Mom like Mommy or Mom is a word that means only a blood relation between mom and son?
Thanks to everyone who will help me to clarify this

Yukk, i find these words gross in the world of sex, people using these words have some serious issues .I always avoid them and i tell off to those that dare to use them in my room. I don't risk getting banned and beside that i despise them.
