The hilarious thing for me is that the Lardbehemoth saw that she disgusted someone just on sheer sight.  Someone she didn't know.  Someone she'll never talk to, or interact with again.  This human just saw the creature and was DISGUSTED by it.  The fat around it's brain didn't allow the processes to muster up, "Fuck me.  I think I better do something about all this fucking blubber."  No.  The buttersmudge gets all uppity that a normal human was disgusted by the jiggly mass lumbering, laboriously, down the damn street.
