Deviant: A thing, phenomenon, or trend that deviates from an expectation or pattern. You are on a deviant touhou imageboard, calling something/someone (who is the target?) a deviant. That's like going to a gay bar and calling someone a faggot.
Yeah, I was referring to the koyukkuri. It seems that my limit of "gross and disgusting" is at the sight of yukkuri babies asking for dickings. I guess I'm just weird that way.
