biebergasm 

Made up on twitter, it is a type of orgasm people get when they see teen popstar sensation Justin Bieber. Justin may even get these himself time to time.

Justin Bieber Fan #1: OMG! Justin looks sooo hot here!! :0

Justin Bieber Fan #2: It looks like he's having a biebergasm! mmmm.

Bieberize 

To digitally slow down a familiar but horrible pop song by 800% so that the artist is unrecognizable, but the production and sound quality come forward to create an ambient, zen-like and beautiful sound.

If you bieberize Justin Beiber's "U Smile," ... I actually like it.
