this is the 90s: YouTube video
and also that thing when you put your arm in your jumper and punch so it looks like your heart is beating out of the body (like in cartoons)
i would say i grew up in the 90's even though i was born in '77.
I was 13 in 1990, and obviously still a kid in the 80's, i remember some stuff as a kid in the 80's but the 90's is when i got a little more freedom; became a teenager and was able to do more and experience more and became fully enveloped in 90's culture more than i did 80's culture. Followed by turning 18 in '95 and 21 in '98.
The 90's was the most memorable and most fun decade i've experienced thus far.
