When legendary female roles are cast for movies, they're more likely to cast Angelina Jolie than Calista Flockhart. In these instances, there is a liberal release of imagination and wishing upon a star going on.
Here's a representative fantasy girl: tall, stern, brunette, wielding a large sword. She could probably best you both in math and in arm-wrestling! Besides, she has great legs and is not loath to let you know it. Definitely she is a fantasy girl for guys; she's not wearing outstanding shoes! We would incorporate some F*** Me Shoes as part of the fantasy. It's part of a winning through intimidation strategy.
Whether an Otaku or a Heisman-seeking football player, always go for the Gold when making up a fantasy girl!
But what about those truly imagination-deprived guys out there? They must make do however they can. Could there be someone out there that has fantasies about Rachel from Cardholders Services? I'm sure there are people who wonder about her. They obviously need help. Especially if they give her their card number so that they could talk dirty to her.
