Flash Nostalgia

Flash Nostalgia is a sudden rush of sadness you get when you experience something (typically a song or an old picture/video) that reminds you of your past. You reminisce about the old times, good or bad, and wish you could slow down or reverse time and make better choices.

Did you hear that they played Hey Soul Sister at the assembly yesterday? haven’t heard that song since like 2010. Shit gave me flash nostalgia.

Ugly Nostalgia

1. A homesickness for something that causes pain.

2. A sentimental longing or yearning associated with a memory despite negative feelings associated with it

3. A nostalgia that is so ugly you can’t look away.

Damn this song I used to listen to when I was depressed has me feeling such a sense of ugly nostalgia. Makes me feel horrible but I can’t stop listening

6-Years' Nostalgia

The six years of permanent nostalgia you gain before existential realization. This mostly occurs between 4 and 10; though can bleed between and outside years.
Nostalgia is mostly found in non-dynamic music and environments, and their iconic features defined in your childhood.

A famous example of 6-Years' Nostalgia happened between 2008 and 2014, with gen-z of this time frame claiming it to be very different from other times.
