"The definition of mantelpiece is a shelf above a fireplace. If you have never seen a fireplace, think of a ... what mantelpiece means as an idiom inside a public bar..(Oh, I get the drift. I also spell pronunciation correctly, finally!)"
To put folk out of their misery it's "who looks at the mantelpiece when they're stoking the fire", and its a BrE expression used by guys to mean "who cares if you girlfriend has big breasts, when you're having sex", often used by one guy to another who's started going out with a petite lady.
