1. Gen Y's undying nostalgia and sorrow over the the loss of Surge.
2. The concept of the Spice Girls' "Girl Power" being a form of feminism.
3. Hanson. Gen Xers: Ask not, "What is an MMMbop?" for one does not question the MMMbop.
4. Coachella. And where all the flower crowns came from.
5. The Pacey vs. Dawson debate. You at least know who these people are, right?
6. Pogs. Although to be fair....most millennials didn't really understand how to correctly play this game, anyhow.

13. Abercrombie & Fitch ads. And why Gen Y kids collected them.
14. Justin Bobby and other MTV reality show characters who were famous for no apparent reason at all.
15. A/S/L. This joke/reference often falls flat with the Gen X crowd.
