The act of Assassinating or being Assassinated in the Halo series. Unlike being Assassinated, this induces a feeling of being raped from behind by a 7 foot human tank with an aftertaste of Where-The-Fuck-Did-That-Come-From.
Player 1: "Ugh, you Assinated me! Thats so cheap you n00b. I'm calling Bungie!"
Player 2: "Yeah, yeah. Use your motion tracker and maybe you'll see it coming... Your still gonna get raped though. Just thought you'd like to know."
