HAD to ROFL...

the ". . .MAO" being purely optional and dependent upon purity of thought.
Since the phone number was a mobile there was NO clue from it, and NO visible land site. 
Instant reaction - ROFL. "I BET they're West Cumbrian."
Just looked them up. Definitely "Marraslavian".
"Over West" tends to use Marra more than other parts of the county; though I suspect it's spreading.
I divide them into two:-
Inner Marraslavia - The Workington area = nearer "home" than
Outer Marraslavia - Whitehaven and beyond.
This was from Inner Marraslavia.
