Event Horizon 

The definition of a shit that is so large in mass that it rises over the water in the toilet bowl. To do so one must shit so that there is a solid base under the water level.

"I just saw an Event Horizon!"
"What? The movie?"
"No! In my toilet!"

Event Horizon 

The moment after you ejaculate where you can’t physically go any longer. No matter how hard you try you can’t get past that point, hence “The Event Horizon.”

“I just got to the Event Horizon oh shit *ejaculates the alphabet onto the Brazillian Flag*”

The exact moment in time between when a person realizes that they are going to have diarrhea and that it is inevitable.

In physics, the event horizon is the "point of no return" in which an object is caught in the gravitational pull of a black hole.

Event Horizon 

The original definition is:
"The gravitational sphere of a black hole within which even light cannot escape"
-Wikipedia

However, recently, a new definition has risen meaning something completely different:
The Event Horizion is the point at which a person is too drunk or stoned to be able to function properly, yet alone remember anything the next day.

Example:

Dude 1: *takes-drag-from-J*
Dude 2: "Oh shit, you don't look so well..."
Dude 1: *falls-off-chair,-blissfully-passes-out*
Dude 2: "Damn that lucky bastard, he just passed the Event Horizon!"
