Hmm, here are some 90s(/early-2000's, I'm young) memories. They might not apply to everyone though, because I'm Australian and we have different products and such..
1. Being jealous of friends because they owned a Gameboy, even before the colour ones (..but I got one
)
2. Remembering when Pokemon was on prime-time on channel 10 (It was also on Cheez TV, though).
3. Watching Cheez TV (now called Toasted) or The Cool Zone.
4. Thinking putting body-glitter all over your face and "sticker" earrings on the side of your eyes were cool (I still do. Sorta XP).
5. Having a Dollarmites account (I didn't have one, actually. But my friends did. Although I do remember the mascots).
6. Card collecting!
7. Simpsons comics. =D
8. Eating Bubble-O-Bills (an icecream in the shape of a cowboy's face, and his nose was a ball of bubblegum).
9. Eating as many Warheads as you can.
10. The health-ed bus would visit your school, and they had a puppet Giraffe called Harold. Who never spoke.
11. Space Jam! =D
12. ..And Furbys!
13. The Nesquik ads where the bunny was drinking Nesquick from a pool.
14. Trolls dolls were popular (even though they've been around forever..)
15. There was a Burger King very briefly in Aus.
16. Goosbumps books and the TV show (the dummy scared me soooo much)

19. Those slap braclets that had animals faces on them.
20. Tamagotchi's... and, later on, Digimons.
21. DOOZIES!
22. Yowies and Kinder Surprises.
23. "Cartoon gansta" tops (usually Loony Toons).
25. "Jelly" shoes.
