The permeating aroma that tends to smell of sweat, arm pits and ass that surrounds an overweight person.
We were all crammed on the bus and I almost threw up from the fat smell coming off the lady standing next to me.

contrary to popular belief the term 'fat knacker' is quite often used to insult someone who is not actually fat. But who is stuffing their amply sized gob full of something a fat person would eat.
Implies that they get knackered whilst eating hence the term fat knacker.
Also can be used to describe someone who is just insanely fat and gets tired shuffling to the fridge.

(note: i have absolutely nothing against fat people, the term fat knacker would only be used (in my case) to describe someone fat and a total ass wipe)
WTF! you're going back for another hamburger? you better hurry up and eat that then you fat knacker!

Me: Shut the fuck up you fat knacker!

This definition is specifically related to the decks and presentations used in corporate, government and other sectors.

FAT is an acronym for:
Flowful(F)
Aesthetic(A)
Thorough(T)

According to the FAT Theory : A good deck should have these 3 elements. For eg: The various individual slides should be in a flow communicating a bigger picture. The deck should be aesthetic, more visual than textual. And most importantly, the data in the slides should be thorough!

This is such a FAT Presentation/Deck
