In George Orwell's Road to Wigan Pier he writes these words, quoting someone and then commenting
'Have another cream cracker, Mr Reilly. You'll like a cream cracker with your cheese' - thus glozing over the fact that there was only cheese for supper.
It is, of course, just an archaic form of "glossing" in the sense of underplaying or minimising. It is in Milton's Paradise Lost"For man will heark'n to his glozing lyes".
