A variety of punk rock originating in the US in the early '80s. It involves shouted vocals (as opposed to growled) with a fast, aggressive tempo and a guitar sound featuring quick chord changes. Minor Threat, Bad Brains, SSD, and the Circle Jerks are known for this style. By 1986, a new style of hardcore came out of the New York scene. The NYHC scene added mosh breakdowns to mix, but the music retained its fast aggressive nature. This spawned the youth crew scene, a positive straight edge scene featuring such bands as Youth of Today, Chain of Strength, and the Gorilla Biscuits. Judge is a notable band from this era that added some metal style to their riffs. In the 90s hardcore took many different direction, bands like Lifetime and Turning Point took the late '80s sound (particularly the melodic approach pioneered by the Gorilla Biscuits) and added a softer sung vocals and the lyrical approach of DC bands like the Rites of Spring and Dag Nasty. Other bands like Earth Crisis mixed hardcore with death metal growls and slow brutal guitars. Today many bands continue to play the early '80s fast, thrashy style as well as the so-called '88 or youth crew style, while still others have taken the sound of bands like Earth Crisis farther and mixed in more metal elements such as double bass drumming. Hardcore refers to all of these styles, though metalcore is best used to identify bands like Throwdown or Converge (who don't really sound anything alike but both mix metal and hardcore). Finally, some bands like Bane, With Honor, and Comeback Kid are mixing positive youth crew style hardcore with more complex metal riffing without straying into the beatdown, double bass drumming style of metalcore. People talking about old-school hardcore should be referring to one of the hardcore sounds that developed in the '80s, regardless of when the band formed.

When one takes an already dangerous activity to an illogical extreme, often ignoring danger, pain and the potential for marked agony.
When Laura overshot that jump by 5 feet and smashed into that tree with her shoulder it was fucking hardcore. I would have her children even though I'm sure she would mercilessly beat me.

1.) a musical genre, the in-between of punk and metal. Hardcore is NOT the music of the pig squealing myspace whores with scene haircuts, though many believe it to be so. Hardcore music typically consists of simple power chords repeated in variations, simple yet loud drums, and a vocalist yelling, not screaming, about either how straight-edge he is, or how straight-edge he isnt. hardcore is NOT abreviated "hxc" and is not spelt hardxcore. Hardcore fans typically wear camo shorts or tight black pants, black shirts of their favorite bands or funny things (like the "spread the joy" shirt from locoroco, not a "how to win at videogames" shirt you bought at hot topic while you were buying your sister new make-up to replace all the eyeliner you stole from her), and occasionally a bandanna around their head, not their neck, and PUMA, NIKE, ADDIDAS, or VANS shoes. Hardcore fans do not wear suits or ties, do not cross-dress, and do not think its cool to kiss guys, even if they're anti-homophobic.

2.) an adjective to describe something done that most people do not have the balls to do.
1.) "Mickeys crew is a hardcore band"

2.) peeing on your friend's sister because she stole your money, windmill kicking your refridgerator open so hard that the container of milk flies out of the door-shelf and into your hand, then ripping the lid off with your teeth and downing all 2 gallons in a single sitting just so that your little brother won't have any milk for his cereal when he wakes up.

Type of punk rock that relies on heavy, rapid-fire delivery.
The Dead Kennedy's IN GOD WE TRUST, INC. EP relies mostly on old hardcore riffs rather than the snazzy hooks the band is best known for.

A style of rock that originated as a variation of punk rock in the late 70s/early 80s. This variation was a harder, heavier version of punk. It is a largely underground genre of rock. Most of the greatest hardcore bands were in the mid-80s.
Rise Against is an example of modern hardcore, whereas Atreyu is mistakenly labelled hardcore.

Black Flag was one of the first hardcore bands.

Hardcore is a term used to justify some dislike. This term is often used by those who are not "hardcore" but want others to believe they are. Bands are often critized for being "not hardcore" because they are vastly more successful than the people bitching about them.
Steve: That band sucks ass they arn't even hardcore.
Brian: Your just pissed cuz they don't live in their parents basement anymore...like some people i know. (looks at Steve and winks)
