Meaning What ?

''mon dieu Rodney, mon dieu''

A classic example on using words that have other meanings but you know exactly what Del Boy was saying. Its like another language - a language of understanding in the deeper sense.
How often our meanings become mis-intepretated - '' oh I thought you mean't this ... - i bet you've heard that before.

Anyhoo heres the question -

carravaggio mes amis

Perhaps the simple term 'Spag Bol' to describe the cusine of choice for the low-budget cook....
