Hal

1. The HAL-9000 computer, guardian of the spacecraft Discovery in the novels and films of 2001: A Space Odyssey and its sequel, 2010. First activated at the HAL plant in Urbana, Illinois on January 12, 1997 (or 1992 in the film version). HAL is short for Heuristic ALgorithmic, and not derived by moving one letter back from the initials of IBM, as some have suggested. HAL's apparently psychotic behaviour in 2001 is revealed in the novel, and in either version of 2010, to have been a result of a neurosis arising from conflicts between his programming to accurately input, analyse and output information, and the demands of national security mandated by the Pentagon.

2. Any troublesome, wary or otherwise bloody-mindedly unhelpful computer.

Open the pod bay doors, Hal.

Hal

The most wonderful boyfriend a girl could ever ask for. No one is better then him. He is the prime example of a girl's perfect boyfriend. He's sweet, compassionate, caring, creative, silly, fun, and gorgeous. His hobbies include mixing bad drinks, airsoft, video games, and hanging out with his girlfriend.

I'm so jealous, I wish I was dating a guy like Hal

Hal

one who absolutely dominates, usually in a charming and sexy way.

"When pinned on the living room floor after a failed wrestling match, I announced he was a Hal and was finally free."

Hal

A tall, assholish poser who puts down people shorter and different than he is, one with a band of suck ups that make him feel so good about himself. Tommy, his right hand man copies whatever Hal does and has no mind of his own, and when he is wrong, doesn't admit to it, Charlie thinks Hal is the coolest guy in the world because he has a mohawk...Charlie also never washes his hair. Hal treats girls nice to their faces but badly behind their backs.

Person 1: Hey, let's go talk to Hal!
Person 2: No, he's a fuck head

Hal

A type of person, almost always the butt of every joke in a group setting.

Jake: Do you remember that time someone was impressed something made it onto Urban Dictionary? Anything can be put on Urban Dictionary!

Ali: Haha, yeah bro, such a Hal Thing to do

Hal Jordan

1) a comic book character who doesn't take shit from anyone, including old people; has punched Batman in the damn mouth for talking back to him

2) possesses a ring that creates green constructs and runs on will power

I asked Hal Jordan to save my house from burning down, but instead he punched me in the face and ganked my car.
