Abbreviation for "Vivziepop
Stan".
A vivziestan is someone who doesn't just like Hazbin Hotel and Helluva Boss, they think they're the best shows ever in terms of animation and writing, and any criticism of these shows
will either get you dogpiled on Twitter, harassed in
DMs, or even doxxed. Doesn't nmatter how minor, major, constructive, or destructive the criticism is.
They also worship Vivienne Medrano like the second coming of Christ, and will
white knight her like such. Doesn't matter if she openly defends somebody getting doxxed because he had political opinions she disagrees with, or if she Tweets the worst, most chronically online hot takes. She could commit a literal warcrime, and these vivziestans
will defend her, at all costs.
