1. A phrase added onto a sentence or story when the content incites excitement or emotion too extreme to be accurately conveyed by verbal description.

Not to be confused with You don't even know, which suggests that the emotion or sensation cannot be described not because it is too powerful but because it is unique to the person experiencing it.
