Judge fails to unravel rap lyrics:

The judge said the claim "led to the faintly surreal experience of three gentlemen in horsehair wigs [himself and the two barristers in the case] examining the meaning of such phrases as 'mish mish man' and 'shizzle my nizzle'."

In any event, the words, although in a form of English, were "for practical purposes a foreign language" and he had no expert evidence as to what they meant.

The case was a defamation of character suit by composer Andrew Alcee against Heartless Crew. The judge apparently had to resort to The Urban Dictionary to try to sort things out.
