An item that can be found on the hidden "McDonald's" menu. You walk into your local "McDonald's" restaurant. You quietly get the cashier's attention and whisper,"I'll have a McDeepthroat please." The cashier then pushes a blue button found under the counter. Next, a naked masked man rushes out of a room in the back at full speed, clears the counter and shoves his cock down your throat. This menu item was first discovered by Kermit the Frog in 1986 while doing a stand up act in Norfolk, Virginia. Despite this item's violent, and quite uncomfortable, taste it is still ordered by the occasional soccer mom.

Briefly, "the realization that each random passerby is living a life as vivid and complex as your own." Originally from the Dictionary of Obscure Sorrows, which has a lot more beautiful neologism definitions like this you might enjoy.
