Person 2But your 35
Person 1Yeah so what
Person 2Your such a Bieberphile
A female from the age of 18 upwards (or in some cases a male) who has an unnatural, creepy and quite frankly unhealthy obsession with canadian singer Justin Bieber. It can also refer to someone who is crazy enough to listen to his music.

Rational Thinking Male: You are such a bieberphile
