a man’s hairstyle that is bald on the top but with long stringy hair hanging over the collar in the back (elderhostel up front, party in the back)

This is a modification of the 80’s mullet. It is worn by the diehard that refuses to give up the long hair that he sported back in high school.

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.
