biffed it

To fall on your face or in an absolutely ridiculous fashion, often suffering and being badly injured in the act.

Boy runs into a tree and breaks his leg.
"Wow, that kid totally biffed it!"

You fat biffer 

Someone eating or aquiring comically large and/or frequent amounts of food, or appearing to do so.
Must be said with a south-west english accent (Cornwall, Devon, etc.)
Only works with the 'You' at the front, and only happens with 'You' and 'Bif' on one note, and 'fat'and 'fer' on a higher one.
There's no real emphasis anywhere, and it's deadpan despite the humourous intent.

"4 pints. And a pie."
"You fat biffer."

BiffedHawn 

The hand with which you have rubbed the head of you're unwashed penis to climax is known as the "BiffedHawn" - e.g you have Biffed yourself hand-wise, self abuse. It now has a vomit inducing scent that should be washed more thoroughly than a coughed in hand.
