Phantom Rider 
You are already booped.
Six-way marriage between Starlight, Sunburst, Twilight, Spike, Trixie, and Maud.
...Of course, Maud would also be married to Pinkie, Spike would also be married to Rarity, Ember, and Applejack, and Twilight to the other mane six and Moondancer.
[throws in other gens for the hell of it]
And Pinkie to Minty, and Moondancer to Glory, and Glory to Applejack.
The wedding cake looks like the one from that one Steven Universe episode.
