I worked with a woman who called her husband by his full name, everytime, along with "big" because they'd called their son after him and he was "wee" so he was "my big John Smith" (not actually John Smith, but you get the drift). So if he'd made the dinner it'd be "my big John Smith made lasagne last night..." or if the teenager did something wrong it was "my wee John Smith is grounded because he came in late".
It was constant and so irritating because she rabbited about the two of them all bloody day long.
