The most brutally honest and cut-throat YouTuber in existence. Also known as Greg Jackson, he doesn't give a shit about hate he receives and regularly makes fun of Emos, cutters, and basic bitches, but not limited to feminists and anorexics. If you don't want honesty, don't watch a guy named Onision.
Shane: "Omg guess what. I kissed Onision!"
Friend: "That insulting faggot who has strong opinions and roasts me with honesty in response to my retarded hatemail? Ew!"
Shane: "Yeah! He's great, isn't he?"
