Do you really have to ask? The '90s!
I HATE the '80s. I hate the music, I hate the clothes, and unfortunately, both have been very trendy the last few years.
My reason for hating the '80s? Other than the songs being cheesy and the clothes being loud and obnoxious, anything from that decade reminds me of being a child. As a kid, I was a big nerd; my mom made me wear some terrible outfits and wouldn't let me pick out my own clothes.
One time I heard a radio deejay make a joke about this very subject. He commented on how the music of the '80s was all peppy and upbeat, and then the '90s came and everybody was all miserable and wanted to just kill themselves. I guess I prefer the darker, more grungy music.
