A person who epic fails, especially in computer fighting games.
i.e. I was playing Halo 3 on XBOX with a mate of mine. i have an energy sword, and he just has a lame old pistol. i lunge at him, point ****ing blank, but epically miss. he just whips me once with his pistol, and pwns me in one hit. This, therefore, makes me an epic fail noob.
