A driving term for when someone wishing to turn left at an intersection quickly pulls through as soon as the light turns green, not allowing oncoming traffic going straight to clear first. This violates the right of way, is illegal and dangerous.
Sometimes it is used with the logic that it's better than you waiting for a whole line of cars to clear and potentially missing the light. Sometimes it is used because you're a douche.
The term is derived from golf; because a hook (as opposed to a slice) is when the ball takes a sudden undesirable left turn at the green.
I don't know, officer. I knew I had the right of way so I just went straight and t-boned the guy. I think he was Hooking the Green. When is that ambulance going to get here?
