Ricky: damn! that man really needs to get laid!

An evolved form of banter. It is often thought to have stemmed from a single being, often referred to as 'the Banteray'.
The phrase began its life as a mistaken corruption of the word banter, thereby creating banter by merly existing, the phrase's banter level have therefore grown exponentially from it's creation.
The recursive property of the phrase means that by the year 2013, it is expected that the word itself will no longer be comprehensible by the human mind. Therefore it is paramount that this phrase is only used in situations of extreme banter.
