Cockney phrase seen in the film "Football Factory"; used to convey one's wish to make love to a pretty lady.
"My gosh Edward, look at how utterly desirable that lady is, I'd love to 'smash the granny' out of her"
"I say old chap, did you 'smash the granny' out of that lass from the croquet tournament?
Why yes, yes I did as a matter of fact
Oh jolly good you sly old dog you, let's drink some Earl Grey in celebration"
