rainbowcake 

A situation "goes rainbowcake" when a perfectly innocent, frivolous conversation suddenly explodes into discord and strife; particularly when it becomes a political argument that never seems to end. While applicable in real life, rainbowcaking most commonly occurs in internet threads. The correct response when someone begins to rainbowcake you is to say "until it's frozen!" It spawns from the great rainbowcake apocalypse of 2014, which can be seen on The Concourse by googling "rainbowcake apocalypse."

The discussion about the relative cuteness of puppies versus kittens went all rainbowcake when Harriet called Abagail's viewpoints on the fluffiness of her tail taoist communist propoganda perpetrated by the lamestream media.
