Robespierre coming down the mountain 

When you realize someone you had respected has lost their mind you would refer to them as "Robespierre coming down the mountain" in reference to Robespierre's Cult of the Supreme Being festival in which he appeared at the top of a 'paper mache' mountain constructed in the center of Paris in a toga and decended to give a speech. Many saw this as proof that he thought he was more than human and had lost touch with reality.

"Oh, here's Robespierre coming down the mountain!"

The Second Coming 

After you've taken a shit and are ready to leave the bathroom, you are struck with a crucifixion of your internal organs causing you to shit a second time and repeat the pooping process over again.

"I was about to leave the bathroom when all the sudden The Second Coming took place upon my bowels."

coming out of the cupboard 

"coming out of the cupboard" is a figure of speech for popular or non popular people's disclosure of their secret obsession for Harry Potter.
The term comes from the well know phrase "coming out of the closet" which refers to a person revealing that they are gay/lesbian.
The "closet" part is replaced by "cupboard" because, as we know, Harry Potter lived in the "cupboard under the stairs" in the beginning of the book series.

I guess I'm finally coming out of the cupboard. I didn't really want people to know I was secretly obsessed with Harry Potter
