Fat cunt syndrome 

Some one who is that fat and ugly, they think they have the right to talk shit about others because their life is that boring and unpleasant 1- because they are overweight

2- because they literally need to put others down to feel better about their fat cuntness

Damn you must have fat cunt syndrome

Fat Smell 

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.

Man did you forget to take a shower or is that just your fat smell?

fat knacker 

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!

Fat Person: 'Ha! look at that bitch Lucy over there'
Me: Shut the fuck up you fat knacker!

Fat Wagon 

Electric wheelchair provided by supermarkets and theme parks, used by people who are not actually disabled, just horribly and grossly fat.

I can't be bothered to walk around DisneyLand all day, I'm going to hire a fat wagon.

fat fuckery 

The act of engaging in activities that only a fat fuck would engage in, i.e. being fat and annoying.

That fucking fat fuck won't bang his hot ass wife just because he has PTSD. That's some serious fat fuckery right there.
