emo
The other 1200 definitions explain the term itself and its origins better than I can here, but it is important to note that the music and accompanying culture currently labeled "emo" by the press and popular media (as well as by the kids themselves) is essentially the same music and culture we all would have simply referred to as "alternative" a decade ago, and which has been shoveled into the media-created pigeonhole formerly occupied by the (arguably artificial) subgenre of "alternative" music known as "grunge" back in the '90s.
My sister's boyfriend swears he's too emo to watch MTV, but I know he got his Vans at the mall.
