unfappable

Something so sexually undesirable, abhorrent or repulsive that it cannot be used for masturbation purposes.

Opposite of fappable.

Guy #1: Did you see "About Schmidt"?
Guy #2: Jack Nicholson and Kathy Bates? Jacuzzi? That shit was unfappable.

Uncanny Valley

First theorized by Japanese roboticist Masahiro Mori in 1970, the Uncanny Valley basically states that the closer a robot or other nonhuman entity gets to resembling a human, the more humans will like and empathize with it.

However, there is a point in development where humans instead become strongly repulsed by the barely-human robot/entity. Fortunately, this effect fades as the robot/entity becomes less distinguishable from a human.

Although hotly debated, the theory is present in many sci-fi movies and the like, and has been used to explain people's reactions to some computer generated characters.

I can't get into "Rumble Roses" because the girls just don't look quite right to me. I guess it's the Uncanny Valley at work.

uncasualify

Go back to playing World of Warcraft hardcore so you can pwn faces and take names.

DBX is going to uncasualify himself, too bad he still sucks.

unappetized

When Paul sneezed and food came out of his mouth, I became very unappetized.
