Dr. Lawrence W. Johnson 

Was a pivotal founder of the hyphy movement during the 1980's. Was most noteable for the extensive amounts of black pussy he got during his visits to the hood. In fact during an expedition to south bronx in the summer of 1983 he was quoted as saying "im thoroughly knackered from all this rigorous sexual activity with the natives". He died on the 13th of January 2005, from what can only be described as death by "schnoo schnoo".

Horny Lass: Boy im looking for some action.

Innocent By-Stander: Why it sounds like you need a dose of Dr. Lawrence W. Johnson. He's got a sexual appetite which is yet to be satisfied.
