- n. Alternative form of knocker-up.
Sorry, no etymologies found.
Although, in justice, we ought to take a moment to admire the easy sophistry of the simple-minded, as Sarah Palin protested loudly to the media that her daughter and her knocker-upper weren't high school dropouts.
It must also have been the media that knocked up Palin's underage daughter, staged and then cancelled a shotgun wedding, then had the nerve of getting the mother of the knocker-upper arrested on charges of selling drugs.
Having said all that, I’m not a knocker-upper (not many people in North Carolina vote Lib Dem) so I may be talking tosh, but I have thought similar thoughts (mainly around the time of the bones commission as people were complaining about EARS – it seemed possibility to build data analysis techniques into its successor).
