Low Knocker

Someone who has very little expectations for himself. No drive or ambition.

"You going out tonight, Susie?"

"Yeah, I got a date with Johnny!"

"Johnny? Geez, does he even have a job? I'm surprised you can pry him off of the couch! He’s 26 years old and still living with mommy. Last I heard he didn’t think there was any reason to even try to get out on his own or nuthin’. He’s got about as much ambition as my pet Goldfish”

"I know...he really IS a Low Knocker, isn't he? What was I thinking?!"

"I can't answer that, but call that Low Knocker back and break it off. You can do better, Susie. Much better!"

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!
