America

The result of failed contraception in Britain, France, Spain and Africa's incestual love affair orgy which created a life-form as flawed and corrupt as all of the participant's put together.

They called it America and left it to verment for a while when it started crying. It eventually got really fat, ugly, thin, beautiful, liberal, extreme, god-fearing and atheistically-insane all at the same time.
Mother 1- Can I see a picture of your eldest.
Mother 2- (Embarassed) Ok.
Mother 1- Wow... she is sure a...
Mother 2- Yep, she's an America.

Lukey English- I'm off to America then, Dad.
Jake English- Be careful, son. You could become a God-fearing super rich movie star or become a father to your sister's mother's uncle's baby in a caravan park in new jersey by the flip of a coin.

blow job

In their second album they abbreviated their band name to "BJ".

Their first album was called "You can feel spots" and had hits such as "get away now", "crabs" and "could just be pearlies".

Their second album was titled "I'm not sure", and contained two hit singles- "Do I like the taste?" and "It went up my airpipe." There was a critically acclaimed bonus track titled- "this is all an innuendo."

A terrible, terrible band.

Flafro

A flat affro. This phenomenom often occurs when a human with an affro sits or lies down and rests their head against a surface that gives greater resistance than their hair. This gives them a flat affro, and this does not right itself until the wearer of the affro fluffs up his/her hair. The degree of a flaffro can vary.
