The battle cry for idiots everywhere. Made famous by the "musician" (if you can even call him that) Soulja Boy. Usually used when telling somebody to Crank That (insert whatever the kids these days Crank to here).
The prime example that a fad has gone too far. Usually done by 16-year-olds who think that Soulja Boy is the best thing since sliced bread. Sometimes done by grown men who need to seriously stop listening to Crank That and get a job.
