i'm not going to explain, if you want to learn, prepare to get a shit load of thumbs pointing down.. since it arrived, it was okay at first, but then it got overused. people were making comics about it, and that made people roll even more! then Carlton Banks just made 2 more rolling abilities! if you want to roll, thats fine by me, but be prepared to see alot of red thumbs..

I hate seeing this...

it's *roll picture*

Hope it helps
