A Jockalypse Now - that's the Scottish National Party buzz-phrase as they and their legions bask in the afterglow of turning Scotland yellow from the glens to Glasgow and back.

Turning a racial slur into a badge of victory, jock being a derogatory term for Scot, suddenly it's all Francis Ford Coppola as Nicola Sturgeon's 56 members of parliament head south to break the Westminster mindset - A Jockalypse Now.

That's the confidence, cachet downright choppiness that winning 56 out of 59 seats in a country gets you.

But ...

One big problem looms for the SNP. They represent the highlands, islands, urban housing projects, city centres - they represent everywhere let's face it.

And ...

They face a massive language barrier.

You see Westminster, London and England generally have real issues when it comes to speaking their language and understanding them.

The British Establishment in the shape of David Cameron's Conservative party seems to have profound difficulties here.

It's not that the English Establishment is tone deaf to the SNP. They really don't get the lingo at all.

For example, throughout this campaign, the SNP has plainly been talking about one thing and the English Establishment has been talking back at them about something entirely different .

Sturgeon's number one campaign manifesto issue has been to fight against cuts to welfare and social spending imposed by Cameron's Conservative government over the past five years.

She has said about 123 gazillion times:

"Even if we win every single seat in Scotland, which we won't, that would not be a mandate to have another referendum on independence."

Yet Conservative and Labour leaders alike have popped up all the way through the election campaign to warn darkly of the threat to the Union and even the (non-existent) British constitution should the SNP win the vote.

Somehow this major comprehension-block has to be climbed over if the yellow SNP of Scotland and the blue Conservatives of England are to do business going forward.

What the English Establishment doesn't get is that the SNP are about a broad culture and political zeitgeist - the Establishment too often see them simply, narrowly and quite wrongly as a campaign for independence pure and simple.

If the latter were true you would not see a 20-year-old student with upcoming exams evicting a sitting MP who was the Labour Shadow Foreign Secretary.

If it were true, how come it took the Labour Party in Scotland generations to see off the Tories here - the SNP have annihilated Labour here in five months.

Why? Because Scotland is witnessing a wholesale mass rebellion against austerity policies but moreover against the entire Blair-Brown New Labour project. Labour is seen as the party, which sold people out to Tory welfare cuts.

So it is about way more than the dream of independence.

Alarmingly there are few signs yet that political leaders will learn or are even interested in learning what these 56 new MPs are about.

Take election night. You have the defeated Labour leader Ed Miliband saying his party has been obliterated in Scotland "by a surge of nationalism" .

Moments later up pops the Conservative MP and London Mayor Boris Johnson saying they must talk to the SNP about "federalism" which would be "simple".

You what? Federalism? I don't think I even heard this word in six weeks on the campaign across Scotland from any party campaigning.

The fact is that is was anti-austerity; anti austerity cuts; anti-Trident nuclear missile system and so on. It was a manifesto - in fact - that led to the SNP conquering Scotland .

So the massive tectonic plates now grind up against each other as the third biggest still-UK political party flexes its new muscle.

The inability of the English plate to understand what has happened in Scotland suggests the tectonics could create an earthquake.

True Cameron may soon be indicating more real powers for Scotland including moves down the road towards letting Scots have full economic control over their own affairs. There is conjecture - not even proper talking on this at this still-early stage. And this is where the hope lies, that a historic mandate can be fulfilled north of the border. Cameron will have to move genuinely and quickly on this.

The central principle of the SNP's campaign has been that they can make Scotland's voice heard more effectively in London than the Labour Party has been able to do for years.

It was manifestly not about gaining enough MPs to somehow force another independence referendum out of Westminster. The only times the SNP leadership talked about referendum or nationalism or indeed independence were the occasions when the media repeatedly questioned them on it.

Indeed the hallmark of this election was the SNP endlessly being asked by journalists - this one included - about issues they were not campaigning on!

Why? Because London news editors could not get themselves beyond the independence agenda any more than other slightly paranoid areas of London.

Because the clear danger is that if the English Establishment simply reverts to paranoia seeing the SNP as nothing less than a threat to the Union of the UK that they cherish so much and nothing more, that is what will bring about that very earthquake they fear so much.

So the paranoia must go in England. The psychology that led the ever-brittle Daily Mail newspaper to dub Sturgeon "The Most Dangerous Woman In Britain" must not infect English political bosses any more if they really care about their Union.

Cameron's new mandate should lead him get to know the SNP and understand their language in his own interests, if nobody else's.

As the Mafia say - keep your friends close but your enemies closer.
