Rap rap R A P P Y

This evening as I approached the final stretch of my walk home from work, among the promenading throng on the narrow paths of King Street a curiously dated vision appeared.

A male, Generation X-er garbed in a rapper ensemble including a baseball cap worn sideways (RAD) strutted past, hangin' tough as his legs, arms and hands cut loose through the air no doubt in time to the tune blaring from his ipod into the ear piece whose wire dangled about his chest.

As he caught me eye, he bellowed:

"You ain't fucken cool, man so you can stick it up your arse."

Now to what song could that lyric possibly belong...
