This is a concept I invented similar to pleading the 5th in a court of law where, if you find yourself in a situation, inebriated, whether high, drunk or otherwise and completely at a loss for what your expected to say or do next You can declare: "I plead the 6th" and you are magically off the hook, as this simultaneously informs others that you have blanked out and have no idea what you were just talking about 2 seconds ago, while also relieving you of any responsibility for whatever word or deed would have come next if you had not forgotten in the first place. So, similar to how the witness in court gets to avoid answering a question by pleading the 5th, the stoned/ drunk/twacked out goofball who forgets what they are talking about midsentence during an important conversation or epic explanation is freed of the weight carried by that awkward moment that exists in the seconds that follow the total forgetting of some vital fact.

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.
