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!"
