The origin of the term "emo" came from music itself in the mid-1980's describing hardcore punk. As the music gained in popularity the slang "emo" was born which is the "emotional" term you talk about. Please see above comment by thefunkygibson and Emo (music) and Emo (slang). While I see that you seem to dislike the emo subgenre I am not entirely sure of the relevance to My Chemical Romance. The subgenre for My Chemical Romance is sourced. The community has agreed before to have all subgenres sourced and only alternative rock in the infobox. This consensus can be found in Talk:My Chemical Romance/Archive 2. I am not quite sure what this discussion has to do with My Chemical Romance however, are you wanting this subgenre to be removed? I would just like your objective clarified.   User Talk | Contribs
