A female you don't want to screw. She could be unappealing, not interested, her bothers would rip you dick off. Or very rarely you value this person so much you would rather keep her as a friend , then risk loosing her as a lover.
Why is Judy my friend girl? A piece of as is just a piece of ass, but a true friend is hard to find.
A sexual partner with whom there is no official 'girl/boyfriend' or marital relationship. One has Special Naked Occasions with one's Special Naked Friend
Jo is my Special Naked Friend = Jo and I have sex together but we are not 'going out'
I had sex with my Special Naked Friend last night.
I had a Special Naked Occasion with my Special Naked Friend last night.
A very very very close friend of the opposite sex. A woman is a man's platonic friend if she's his best friend (or a very close friend of his), but nothing more.
And yes, contrary to what's been said earlier, men CAN have platonic friends, just like women.
person1: Ashley and Brandon are so close to each other, they spend all of their time together. I'm sure they're dating!
Person2: Not necessarily, i asked Ashley yesterday and she told me that there was nothing between them, they're just platonic friends.
