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?"

Onision is a man who does comedy videos, music videos and other stuffs. In his videos he tells the truth. Some people hates him because of that. Some peoples gets offended by some of his videos, but he has a warning before (almost) every video that some people ignore. So if you ignore the warning its not Onisions fault that you got offended, its yours.
Person: I hate Onison...he always offend peoples.
Onision fan: Don't watch him then.
