fatslapper 

One who sits around and does nothing useful for anyone when there is work to be done. Thus, this makes the person fatter, and they become proud of it.

"Get off your ass, you lazy fatslapper, and help me move this body into the trunk."

Fat-slap 

The act of offering one's seat on public transport (most commonly the Subway) to a lady who appears to be pregnant but who is, as it turns out, just a bit fat.

John: Excuse me ma'am I see you are with child may I offer you my seat?

Natasha: What, bitch? Are you fat-slapping me!? I'm gonna beat yo' sorry ass!

John: Fuck off.
