Event horizon 

During the final moments before cumming, there is a point in time, that when crossed, there is nothing that could save you from not cumming.

You know that bitch, Sasha Fox, she gave me the event horizon

Non-Event Horizon 

The point at which a friend's Facebook status updates become so numerous and mundane that he or she must be hidden from the News Feed.

"Linda is approaching the Non-Event Horizon. 15 posts so far, most of which have been 'I'm bending at the waist right now.'"

Onion Irrelevance Event Horizon 

The point at which reality becomes so weird that the comedy website The Onion is no longer funny in comparison.

"Did you see that political ad? It's WAY past The Onion Irrelevance Event Horizon."

Shoe event horizon 

The Shoe Event Horizon is an economic theory that draws a correlation between the level of economic (and emotional) depression of a society and the number of shoe shops the society has.

The theory is summarized as such: as a society sinks into depression, the people of the society need to cheer themselves up by buying themselves gifts. This is usually done through the purchase of shoes. As more money is spent on shoes, more shoe shops are built, and the quality of the shoes begins to diminish. This makes people buy more shoes.

The above turns into a vicious cycle, the end result being that other industries begin to falter.

Eventually the titular Shoe Event Horizon is reached, where the only type of store economically viable to build is a shoe shop. At this point, society ceases to function, and the economy collapses, sending a world into ruin.

The population of the planet Brontitall was forced to evolve into bird-like creatures in order to survive the result of the shoe event horizon.

email event horizon 

The bottom of the list of emails in your inbox that you can see on one screen without scrolling or clicking to the next page. Once an email slips to the next screen, the likelihood of a response is significantly diminished.

Sorry, it took so long to get back to you. It was kind of a crazy week and once your email slipped below the event horizon I completely spaced.

Memory Event Horizon 

The Memory Event Horizon is the point where the last person with direct experience of a historical event dies, leaving only second-hand knowledge of the event. Usually applied to wars as the veterans of each war pass away, but can be applied to any significant event that leaves a lasting imprint on a society. Once an event has passed its Memory Event Horizon it will forevermore only exist in history books and documentaries.

When the last U.S. veteran of World War I, Frank Buckles, passed away in 2011 the First World war passed the Memory Event Horizon into history.
