If you've been on Twitter this morning, you might have been greeted with posts proclaiming "Happy Platty Joobs".
And much like Marmite, you'll likely either love or hate this nickname for the Queen's Platinum Jubilee.
The Jubilee kicks off today with Trooping the Colour, where the Queen is expected to make an appearance on the Buckingham Palace balcony and ends on Sunday with the People's Pageant - when we shall see her Majesty once more.
