1. When one is agitated to the extreme and proceeds at going into such a blind rage that seemingly nothing is capable of stopping him/her. Usually the ensuing violence is on a very personal level and the entire group of opponents is always killed or incapacitated. Preferably, it must be so noticeable that the other side of the planet will go “What the hell was that?”
*Based on when Martin Riggs from "Lethal Weapon" gets severely pissed. When he’s “gone Riggs”, gun shots, broken ribs, dislocated shoulders, explosions, and people with diplomatic immunity stand no chance at keeping him at bay.
"Oh my god, he's going Riggs"
What the character Riggs did to the South African diplomats in “Lethal Weapon 2” when Rika (the attractive blonde) was killed.
Getting pissed in "Halo" and as a result of the built up anger, charging the base alone and killing everyone close-up and directly.
