n00bflex, n00bflexes
In a game when basic instincts and/or panic take over, such as wildly sparying your weapon in a FPS game. Note: the incorrect pronunciation of n00b is used here instead of the more proper "newbie"
Ex: "I was playing Counter-Strike and a guy came around the corner, my n00bflexes kicked in, and I just started spraying at him."
