Banana

A banana is a subscriber of onision that watches his videos obsessively to the point where they start peeling of their own skin while cannibalising themselves up to the point of death

Most bananas aka onision fans wind up dead or in hospital due the cancerous affect of his videos. Onision must be stopped

Used in a sentence guy 1: have you heard of onision? Guy 2: oh you mean the next hitler? Guy 1 kills himself as he was a banana
