As far as the culture, a lot of the shit that was goin on when the movement was at it's peak is still goin on. Every house party I hit niggas still dance the same way they was in 06. It's still turfin its still shaking dreads.......but as far as the music that rappers make, it's not the same. Like 510 said rappers out here don't make songs to get people "hyphy" anymore...Rappers aren't telling ppl to go dumb or ghostride or rock stunnas.
As far as Jerkin', that shit has it's own distinct sound. There is a type of beat that every "jerk" song had in order for the dance to coincide to it. I feel like hyphy music was more versatile because it didn't have a distinct sound. But regardless, the negative connotations will not allow it to return.
