as far as emo...
Emo is a subgenre of hardcore punk music. Use of the term (and which musicians should be so classified) has been the subject of much debate.
In its original incarnation, the term emo was used to describe the music of the mid-1980s DC scene and its associated bands. In later years, the term emocore, short for "emotional hardcore", was also used to describe the DC scene and some of the regional scenes that spawned from it. The term emo was derived from the fact that, on occasion, members of a band would become spontaneously and literally emotional during performances. The most recognizable names of the period included Rites of Spring, Embrace, One Last Wish, Beefeater, Gray Matter, Fire Party and slightly later, Moss Icon. The first wave of emo began to fade after the breakups of most of the involved bands in the early 1990s.
Starting in the mid-1990s, the term emo began to reflect the indie scene that followed the influences of Fugazi, which itself was an offshoot of the first wave of emo. Bands including Sunny Day Real Estate and Texas Is the Reason put forth a more indie rock brand of emo, which was more melodic and less chaotic in nature than its predecessor. The so-called "indie emo" scene survived until the end of the 1990s, as many of the bands either disbanded or shifted their style to the mainstream.
As the remaining indie emo bands entered the mainstream, newer bands began to emulate the more mainstream style, creating a style of music that has now earned the moniker emo within popular culture. Whereas, even in the past, the term emo was used to identify a wide variety of bands, the breadth of bands listed under today's emo is even more vast, leaving the term "emo" as more of a loose identifier than as a specific genre of music.

Origins
For more than a decade, the term emo was used almost exclusively to describe the genre of music that spawned from the 1980s DC scene and all of the bands inspired by it. However, during the late 1990s, as emo music began to emerge from the underground into popular consciousness, the term began to be used as a reference for more than just the music.
The origin of the word emo itself is unclear. In a 1985 interview by Rites of Spring in Flipside Magazine, members of the band noted that some of their fans in DC were starting to call them "emo", arguably because of the state of emotion that the band displayed during their shows. In later years, the word emo was viewed as a contraction of "emotional hardcore" or "emocore", which was the popular designation of the music genre. (One contingent of the scene insists that emo is a contraction for "emotive hardcore". However, no primary source has been found to confirm use of that term prior to the mid-1990s.)
In recent years, as its use has come to define more than just the music, the word emo has more often been viewed as simply being short for "emotional".

1990s
With the advent of the late 90s indie emo scene, some sense of commonality began to emerge, particularly in terms of dress. For example, it became increasingly common to see males wearing the "nerd" style of dress popularized by bands like Weezer, including thick black glasses, straight-legged khaki pants, and v-neck sweaters, accessorized with a chain wallet. While the style was not particularly prevalent, people aware of the scene began associating those common styles with the emo bands of the period, and began describing the wearers as "dressing emo".
While it contained some of the elements of passion and emotion that earned the moniker emo in the first place, the indie emo of the 90s was often seen as simply an offshoot of indie rock. Some rock scenes saw indie emo as "hardcore music for nerds", where it was okay to play loud and fast, but without the more "macho" elements sometimes found in hard rock. While it was a marginal viewpoint at the time, it began the trend of people using the word "emo" as a term of derision.

2000s
Bands like Dashboard Confessional began to popularize a more dramatic and personal style of "emo", which contained lyrics that had a far greater appeal amongst teenagers experiencing life and love for the first time. As the lyrical content shifted and as the sound began to enter the mainstream, the term "emo" started to be used more often to describe what was perceived by those outside the scene as the overwrought melodrama of the music. Popular comments such as "don't be so emo" and "cheer up, emo kid" drove home the belief among deriders that fans of emo music took themselves too seriously and were simply looking for drama where it didn't exist.
As major labels began pushing more bands under the "emo" umbrella, varying styles of music and dress began to be lumped in as well. The style of bands like My Chemical Romance, including their use of makeup (particularly black eyeliner) and longish hair covering the face, began to be associated with "emo".
Some of the stereotypical fashion trends associated with emo include the wearing of tight jeans, black clothing, All-Stars shoes, and used T-shirts with random prints. Piercings and tattoos are also popular, especially labret piercings.
Though the original emo scenes were not exclusionary, the modern "emo" scene has developed into a "gay friendly" scene. Though it's unclear whether it's related to the diminished "macho" elements of emo music or the "gay friendly" nature of the scene, it has become commonplace for detractors to use "emo" in combination with popular gay slurs, such as "emo fag".
While use of the term "emo" to describe the dress and attitudes of some fans of emo music, it should be noted that use of "emo" as a musical genre and "emo" as a slang term are largely separate. "Emo" as a musical genre long pre-dated the use of "emo" as a slang term, while most modern bands labelled "emo" are done so unwillingly, and largely because they share some of the fashion trends and attitude associated with "emo" as a slang term.
