hartnett hangover 

How one feels when one is repeatedly POWed unrealistically over an hour and a half, where one's partner then asks "did you have fun??"
I can't believe that how sore I am after he gave me the Hartnett Hangover last night.

The only reason to watch Wicker Park is to obsess over Josh Hartnett more than that stalker-chick.

Josh Hartnett 

Josh Hartnett...ah so many words to describe him. Hott is one of them. Sexy is another. And then there is talented. Known for his great role in The Faculty with that famous line "guaranteed to jack you up." I mean who but him could pull it off? Once the boyfriend of Scarlett Johansson but now he has moved on to some other girls for example Rihanna. Hopefully he will continue in starring on all those great movies ahead of us. Oh and by the way he was born on July 21, 1978.
Josh Hartnett is the god of the actors in Hollywood.

Word of the Day on October 4, 2026
British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.

Pee Calculus

When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
