Def Leppard 

A fairly effeminate feathered hair British band that created a handful of pretty listenable rock songs, overproduced out the ass until they aren't as lame or glammed out. Most people who like this band are annoying women who are trying too hard to be cool. Most people who hate the band don't listen to much outside of either Slayer or on the other end of the musical spectrum some kind of other pop swill like Donna Summer/KC and the Sunshine band.
