Hilarocity 

When something is so funny, the hilaros or "funny" level begins to rise to astronomical heights and the world is forever changed. This often happens when one phrase is used so often it stops being funny, isn't used for several days, then is re-introduced at the proper time.

"Remember when Jansson kept getting so drunk he would get belligerent and then get punched in the face?"
"Man, that was hilaros"
"Yeah... and we called him Black Eye Jansson?
"HAHA BLACK EYE JANSSON!"
"BLACK EYE JANSSON!"
"WHAT AN ASSHOLE!"
"Hilarocity factor of 12 right now"

hilariocity 

Used to define a so-bad-it's-good movie. It's such an atrocity, it's hilarious. Hilariocity.

Did you see The Room? It's such a hilariocity.
The Wicker Man starring Nicolas Cage is one of the greatest hilariocities of all time.

Conditional Hilarity Syndrome 

Where, if you hate someone, nothing they say will be funny to you, no matter how funny it actually is. Additionally, when you like someone, every little thing they say is funny no matter how stupid it actually is.

James- Hey guys look! (makes unfunny face)
Hilary- Hahaha! James you're so funny!

Hank- Man Hilary must really have Conditional Hilarity Syndrome because that was the least funny thing anyone has ever done on planet earth.

Hilarity Ensues 

From the days of newspaper TV Guides that would write two sentence synopses (loglines) of a television show. Sometimes these summaries wouldn't sound comedic on the surface, so "hilarity ensues" was used to ensure the audience understood it was a premise for a comedy.

Tonight on Seinfeld, George decides the best time to have a snack is during sex. Hilarity ensues.

Oh the Hilarity 

A statement used like LOL, being 100% overused in most blogTV rooms, especially lovemedeadx3's, you go in there and you will see that flooded like crazy.

Simply means, oh haha, thats funny.

The damn girl on the camera says it yet doesn't crack a smile. So basically means, lol, which is a filler word for "i dont really give a shit but hah okay."

Person1: Hey I took a dump on the teachers desk in 3rd hour as she taught the class.

Person2: Oh the hilarity.
