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"
