ephemera 

How some psycho girls think of boys: used only for a short time.

"Hi. I'm Caroline. I like that boy. I'll add him to my list of ephemeras."

ephemeral 

1- Lasting for a markedly brief time: “There remain some truths too ephemeral to be captured in the cold pages of a court transcript” (Irving R. Kaufman).
2- Living or lasting only for a day, as certain plants or insects do.

"the ephemeral joys of childhood"; "a passing fancy"; "youth's transient beauty"; "love is transitory but at is eternal"; "fugacious blossoms"

Ephemeral 

Lasting for a short period of time; typically one day.
Or
A short-lived experience.

The feeling was ephemeral.
The spring is ephemeral.
You have an ephemeral experience in life.

ephemeralia 

Assorted objects that people tend to accumulate, like receipts and ticket stubs and tissues.

There was ephemeralia scattered all over the floor of her room.

Ephemerabilia

Objects like groan tubes, bouncy balls and light-up wands you buy in novelty shops that seem great at the time but later you realise is just worthless shite.

Fred:...Why did I buy this Glowing Mickey Ears light up wand in Disneyworld again?
Lucas: Dude, I told you when you in the shop, that's totally just ephemerabilia.
