That one guy who purposely tries to keep in touch with the younger generation despite his old-age status. He is a double-edged sword because, on one hand, his music range involves anything except Nickelback but on the other, his primary source of food is Taco Bell. Either way, you'll be bleeding from the ears or the asshole.
