Event Horizon

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!"

"Once your reach the event horizon there is no turing back."
