Narco/junkie slang for the "crash" after a big high - when you are coming down hard, in physical and mental discomfort, and really have a craving to get another fix so you can feel better. Also, sometimes written as hurtbox
Man, I'm really in my hurt box right now, if I don't score a fix soon, I think I'm gonna die.
A Fighting Game term which refers to the box-like or circle-like descriptors attached to a character's model showing where they can and cannot be hit. When the hitbox of an attack meets a character's hurtbox, the result is a successful hit. Hurtboxes are typically invisible during normal gameplay and do not line up exactly with a character's model.
In Super Smash Bros. Melee, Mr. Game & Watch's shield doesn't cover his entire hurtbox, meaning he can get hit even while shielding.
