Glamour models

[Big King Sanctaphrax]

I guess 'glamour model' is a euphemism for a pornstar.

Not porn, really. Just topless modelling, normally-a bit more risque than swimsuit stuff, but nothing approaching even softcore porn. They mostly appear in Lads' mags and on Page 3 (Page 3 of most British tabloid newspapers, especially the Sun, traditionally has topless women on it)

I really don't think this is do do with her getting the melons out every now and again; it's more about her being very dim and George being a bit arrogant.
