Pyroclastic flow 

Pyroclastic flow is Ice Cube's gangsta flow. It's his ability to rhyme to cool beats, and gangsta lyrics.

Official definition of Pyroclastic flow by Ice Cube :
What's the definition of a pyroclastic flow?
That's what happens when a volcano blow
That's what happens when Ice Cube starts to flow
Red hot lava mixed with saliva
Pulverising everything in its wake
Nothing can survive a pyroclastic flow

Even Flow

This is one of the best, if not THE BEST, songs written and performed by American grunge band Pearl Jam. This song is recognizable for its catchy guitar riff and its hardcore chorus. It appears in Guitar Hero 3 and is one of the best songs to play.

oh, he don't know,
so he chases them away!!!
