Donutable Event 

An event that is worthy of a coworker or manager bringing in donuts to the office in order to celebrate the event.

Gee, we passed that audit with flying colors. Isn't that a donutable event? Hey ask Tom if he is bringing in donuts tomorrow.

Tuesday Evening 

The sexual act of spitting into the lover's mouth after an evening's meal.

Not to be confused with Thursday Afternoon.

Me and my wife gave each other a Tuesday Evening after we had Chinese Fast food.

Wife: Hey baby do you want another Tuesday Evening?
Husband: No, I'm good.

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.
