1. To leave or walk away very angry, especially in a physically aggressive or imposing manner. A reference to The Incredible Hulk, a comic book character known for becoming very large and destructive when made angry. Everyone was expecting a fight to break out, but the guy just hulked off after the bouncer told him to leave.
2. To rip something off (of something) or away (from someone) in a fit of rage. In this usage, a noun or pronoun is used between "hulk" and "off." I had gotten so frustrated by the fiddly lock on the bike that I ended up just hulking the whole thing off the wall.
