A watered-down form of melodic death metal, due to it's lack of keyboard, less brutal vocals, and overall shorter songs. Listened to by scenester kids, along with deathcore, who are ignorant to it's superior predecessor which originated in Sweden.
I used to listen to metalcore bands like All That Remains, August Burns Red, and As I Lay Dying, but now I listen to bands like Children of Bodom, Dark Tranquillity, and Mors Principium Est.

Metalcore is a mix of heavy metal and hardcore music. It originated in the 1980's with bands like Integrity. Metalcore used to be refered to as Cross-Over Thrash, as stated by bands such as Dirty Rotten Imbecilesand Nuclear Assault.

Today, Metalcore and Cross-Over Thrash are considered two completely different genres of music. Nuclear Assault was among the first bands to call themselves Heavy Metal/Hardcore Punk band. Breakdown was arguably one of the earliest to fuse heavy metal-influenced riffing with a more traditional hardcore sound without being a thrash metal band.

Breakdowns are essential part of metalcore. Typically, the guitars play a set of rhythmically oriented riffs, usually on open strings so as to achieve the lowest sound the guitars are tuned for. These riffs are often accented by the drummer with double kick bass drums.
Examples of metalcore are: theBLED, Haste The Day, Bleeding Through, Underoath (Act Of Depression & Cries Of The Past), Killswitch Engage, As I Lay Dying, The Black Dahlia Murder, Bury Your Dead, Norma Jean, The Chariot, Darkest Hour, The Dillinger Escape Plan, Between The Buried And Me, Escape The Fate, Every Time I Die, Evergreen Terrace, Hatebreed, The Haunted, Misery Signals, The Number Twelve Looks Like You, Parkway Drive, Unearth, Vanna, and Walls Of Jericho.

Shitty genre of music. It is said to be derived from hardcore punk and heavy metal, but really sounds like Panic! at the Disco with heavier guitar riffs. The vocalists are usually washed up emos.
Metalcore.

A watered down poor excuse for a metal genre that claims to mix extreme metal and Hardcore punk but really adds Emo, Screamo, Pop and Glam as well. A sorry metal sub genre that falsifies the idea of punk metal into crappy crybaby new generation "brutal" pop metal. Emos and Scene Kids mostly listen to this type of music. Typically, Metalcore = Emo Metal & Deathcore = Scene Metal. Its a band wagon genre like Glam Metal and Rap, people fallow it to the end of its popularity and go back to listening to something usually non-metal related. But not always, sometimes they mature their Heavy Metal music tastes and find better music. Core kids often refer this type of music to Post Hardcore, the name states what it is, "WASN'T" hardcore.
Some of these bands try to label themselves as Grindcore or Thrash but are far from the idea of ever being so.

The genre has motivated a bunch of kids to start these types of bands and fill the underground scene with terrible ill-prepared wanna be in a band type music.
August Burns Red, Asking Alexandria, Bring me the Horizon, Attack Attack, All That Remains , Memphis May Fire, The Devil Wears Prada and Black Veil Brides are uber pathetic talentless Metalcore bands that core kids listen to and try to share with you before you kick their ass.

Metalcore is basically an evolution of the mixing of punk and metal that has been hapening for at least 30 years. In the begining bands like Minor Threat, Bad Brains took on a harsher edge to punk music and played it fast. Their speed influenced the first wave of thrash metal like Slayer, Metallica, Megadeth, etc... From there you had crossover wich was a completel blend of punk and thrash with bands like DRI, Whermacht, The Accused, Attitude Adjustment, etc. Also at this time hardcore was coming into it's own with the likes of The Cro-mags, Agnostic Front, Sick Of It All. Now you add influences of death metal from the early 90's and the fierce speed of late 80's crossover bands like Cryptic Slaughter and grind bands like Carcass and Napalm Death, especially the melodic death sounds sounds of At The Gates and In Flames and you have metalcore. More metallic and generally a more technical style of hardcore with breakdowns and clean sung parts as well for better or for worse.
Metalcore: Killswitch Engage, Unearth, Zao, Lamb Of God, Between The Buried And Me, All That Remains, Misery Signals, The Dillinger Escape Plan, Burnt By The Sun

Hardcore: Terror, Most Precious Blood, Converge, Comeback Kid, Nora
