Wanna start a rumble? Just try getting shady with any of these crews nominated for "Fan Army FTW!" These folks are bonkers, yo! Support! OMAs for days!

MTV's first-ever O Music Awards are coming... People are voting like crazy. Fan posses are battling, crazed ego-hungry celebs are Tweeting, and Vegas is bracing itself for the 28th of April.

There, in some undisclosed location (I'm hoping for the Liberace Museum, but...) an actual OMAs event will take place which will feature live sh*t from the likes of Mumford & Sons, Lupe Fiasco, Lil B, Chiddy Bang, Matt & Kim, Edward Sharpe, Old Crow Medicine Show and Foster the People, as well as appearances by Ke$ha, Cee Lo Green, B.o.B, Wiz Khalifa, Robyn and Theophilus London. PLUS, a Guinness-Book-of-World-Records-breaking freestyle rap attempt by Chiddy Bang!

Go vote for all the freakin' bizarre and fabulous categories: Fan Army FTW, Must-Follow Artist on Twitter, Most Innovative Artist, Most Viral Dance... And yes, Favorite F**k Yeah Tumblr.

You've only got about 7 hours left to vote. Get to it.
