A fan of Justin Bieber that has a taste of music similar to that of the flavor of cow feces. Any believer of Justin Bieber have an IQ that creates a new category in the IQ chart below Profound Mental Retardation and is a negative number or beyond.

Beliebers tend to despise men, haters of Justin Bieber, and have a daily habit of collecting anything that is relevant to Justin. They will deny anything a hater says and will only love Justin Bieber.

Scientists say that beliebers are a sign that the world will end. How this is so is that beliebers will spread their lethal disease known as "Bieber Fever" to other women, which would cause divorce, conversion of sexuality into being a lesbian, dreams of Justin Bieber, and lack of the natural ability to search and mate with males. Then, the beliebers will attempt to go to Justin Bieber, in which she may reject, thus causing suicide from big fans of Justin. This will heavily reduce the human population and thus cause the collapse of civilization and the extinction of the human species.

The only way to prevent this worst-case scenario is by murdering Justin Bieber, which will cause the current beliebers to commit suicide and to prevent the spread of Bieber Fever, thus saving the future generations and bringing the end of the horrible pandemic.
Belieber: I love Justin Bieber.

Also known as breadlibers and duckliebers are the most hated fan-base in the entire world. They have their own Wikipedia page, broke the Guinness Record and own about 86% of Twitter. People are saying that they are obsessed with Justin Bieber (their idol) but in reality they just want to help Justin become more successful.

Not only that but people are also judging the ENTIRE fan-base based on maybe 1-10 people's actions.
I myself am a belieber just trying to get the respect we all deserve but I do agree with some of those people... Beliebers can be a bit... overreacting.

Here's something to the 29 million beliebers :Kill them with KINDNESS

I came up with "Belieber Tease" - someone who claims to be intelligent, but on further investigation, is a diehard fan of the infamous Justin Bieber. Usually comes attached with various forms of "xxx" or "xoxo" in their social network usernames and IM names. Beliebers facebook posts, tweets, or IM messages also usually come laced with hideous spelling mistakes, and illegible forms of colloquialism and colloquial language.
