A combination of Mandy Moore and mandatory, meaning it is necessary to do something if you wanna get with a girl and used primarily in reference to a girl that is so fine it is necessary to get those digits ASAP
Damn man, I saw this one girl at the park today and let me just say, she was lookin' so nice it was mandymooreatory for me to make a move on her dawg.

If you wanna get some brain in the front seat of the hummer, it is mandymooreatory that you treat yo girl with some respect.

Now I ain't she a gold digger, but its mandymooreatory you get a prenup with this girl.
