MTV has announced a second O Music Awards ceremony, to take place just six months after the first. Katy Perry, Justin Bieber, and Joe Jonas are among the nominees for the show, which takes place on Oct. 31 and aims to recognize pop culture contributions that fit the three Os: Offbeat, outrageous, and online.

If you thought the categories were strange last time, when Kanye West captured Best Tweet and Nicki Minaj won for Favorite Animated GIF, check out some of the awards MTV has planned this time around: Fan Army FTW, Oops! I Did it Online Award, WTF I Love This Award, and Too Much Ass for TV.

While many of the categories feature lesser-known nominees whose work may have gone unnoticed until now, some of music's superstars also made the cut. VMA winners Perry and West are contenders for Best Lyric Video for 'E.T.' Their competition includes Jonas' 'See No More,' Christina Perri's 'Arms' and Lenny Kravitz's 'Stand.'

Katy Perry is also up for Best Artist with a Cameraphone, which rewards the artist who tweets and blogs the most interesting photos, but she'll have to contend with Bieber, Demi Lovato, Young the Giant and a half-dozen others.

Another interesting category is Best Vintage Viral Video, which includes the videos of Sinead O'Connor tearing up a picture of the Pope on 'Saturday Night Live' and a 17-year-old Notorious B.I.G. freestyling in Brooklyn.

The last O Awards were only shown online, but the October event will be shown on one of MTV's networks, though the exact time and specific channel have yet to be announced. The winners are determined by fan voting, so get yourself over to to voice your opinion.
