Beibercaust 

An era (early 2000's) where anyone calling themselves a fan of Justin Beiber was kidnapped and thrown into a corrective camp. Each corrective camp was equipped with an enourmous Beiber-removing center. Each hostage would then partake in a Beiber-purging ritual until all remnants of Beiber was removed from their body.

Man, i really dodged a bullet with that whole Beibercaust thing. I'm glad i threw my albums out yesterday.

Biebercaust

The act of attempting to ignoring a person where such act is so heinous that it obviously must be compared to one of the worst crimes in human history.

Joe has been avoiding my calls all day. It's like he doesn't even recognize my existence. This is a total biebercaust.

Biebercaust

Where all the Bieber fans kill themselves or get killed. It is a day of rejoice and faith in humanity to know that these certain beings are eradicated from our society.

NEWS: Bieber smokes weed.
Beliebers: we going to kill ourselves
Normal People: Yet another Biebercaust

Beibernaut

1.) a man or woman obsessed with The Beibs.

2.) A young woman usually between ages 18-25 who has an irrational love for under-aged male pop singers, i.e Justin Beiber.

That girl in our math class is such a Beibernaut.
