emo

"emo" is most commonly thought of as little 14 year olds in all black, black hair, black everything. Often they will cut but most importantly consider themselves emos as they listen to fake metal bands such as:
Pierce the veil
Black veil brides
Of Mice & Men

the list of bands in such "fake poser metal" is near endless and spans from Fall Out Boy style pop rock to Sleeping With Whiners appalling take on metalcore. Emo is used as a half derogatory half label to those who listen to shit; much in a similar fashion to that as the word "nigger".

Originally from the 90s who were offspring of the punk tree, the word was used to describe bands who's lyrical were whilst being hardcore with a punk tint overlapping them. As people denied this tree of punk any right to be called emo and began to focus the word on the above description, emocore as such faded out. However in 2010, a revival began, spearheaded no longer by bands such as I Hate Myself and SDRE but bands such as TWIABP and Everyone Everywhere (bands with essentially the longest most obscure names possible) who's style is defined as lyrically soft often with high treble guitars yet still retaining the original screamo segments or rough quality.

"Dude, I'm pretty emo myself, I listen to Of Mice and Men..."
"nah dude you're just a fag"

Or

"Holy crap, Things In progression of reactivity, that's a long band name. Better get my black jeans, Topshelf Records shirt, band flag and a semi-acoustic and start up an atmospheric emo indie alt band".

Or

"Wow his skramz style is brutal"
"yeah dude, someone said he lost his entire voice for six months after that gig"
"sick, lets shred dude"
"yeahhhhh"
