"You don't want to go in there, I just took a huge Bieber."

A Bieber is a military target that has been obliterated by a hugely excessive amount of ordnance, often fired in a frenzied and uncontrolled manner.
When the enemy entered the crosshairs, I clamped my finger hard on the trigger until the ammo ran out. My target was transformed into one humongous Bieber! The rotary barrel was still spinning long after the last shell had left the muzzle. The smell of cordite emanating from the massive pile of spent casings was intoxicating...

The act of throwing up because something is so horrendous.
If you've ever seen Jersey Shore, then you've probably Bieber'd or have come very close to Bieber'n.
