One who lurks in the corner waiting to steal one's nuts. Typically, found with a computer and a pack of smokes on him.
Hey, where did my nuts go?? There must be a Hartnett near by!

1) A surprisingly talented (and hot) younger actor.
2) Best known for playing a drug dealing alien killer in The Faculty and then acting in a bunch of bad movies.
3) Recently more high profile actor in movies like Sin City, Lucky Number Slevin, and, supposedly, 30 Days of Night.
4) Has a voice that spontaneously causes orgasms.
The only reason to watch Wicker Park is to obsess over Josh Hartnett more than that stalker-chick.

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.

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.

Josh Hartnett's Ernest Lawrence, from Pearl Harbor to nuclear harbor, building bombs with charisma!
Example of how it's used in a sentence:

Person 1: Is Josh Hartnett in Oppenheimer?

Person 2: Yeah! Josh Hartnett as Ernest Lawrence, he's building charisma bombs dude!

Mr.Hartnett is a gym teacher. Mr. Hartnett believes in Woman’s rights way to much for a man himself. He is a huge feminist and is very sexist during his classes. He always makes the girls go first and hates the boys in his class. Mr. Hartnett was born girl and is transgender so now a boy. This would explain his small penis.
Mr. Hartnett is very sexist and is a bad gym teacher who stops every time a girl is not involved in something in his class. He is the worst
