Started by the underground punks in the seventies, but frequently (and wrongly) associated with metal heads and nu metal. Basically, at a PUNK SHOW you and your droogskick the living shit out of eachother during a nice song, say, sex and violence by the exploited.

Mosh Pit Vocab-

The Two-Person Approach- frequently used by first-timers and punk ladies who dont want to get beaten too badly. The smaller of the two partners is picked up by the larger of the two and swung around hoping to kick the pussies and emo kids who aren't in the mosh pit in the face with their steel-toed-boots.

Regular style- at a local show, a bunch of kids kicking the shit out of eachother. Normally started when one runs into another one, (purposefully or not) and gets punched in the face.

Ass Fag Emo Kids- kids who stand on the outside of the pit and enjoy pushing the people, who #1- are trying to genuinely get out because their nose is broken, or #2 just got pushed out by someone else in the put, back into the pit quite hard and quite meanly. If you ever get in contact with one of these kids, push them in the pit and do everyone a favor.

The Light Fixture- One hangs from a light fixture and kicks people in the face. If you are one of these, try to hit the ass fag emo kids so they fall into the pit and get squashed.

The Banana- Throwing a banana into a pit. Sometimes done by AFEK, but sometimes done by cool people who just want to poke fun at their friends. I've done this before. The banana eventually gets diffused around the show, and everyone smells like banana.

The Dominants- The kids you see with the metal-covered jackets with the misfits and buzzcocks and adicts patches on their pants/jackets/shirts/body. with the mo/trihawks and steel toe boots. these kids better get some damn respect, or you'd better fuckin run for your emo life. I know doms that have eaten emo kids before, razorblades and all.

The Initiator- That one guy, who, when the song speeds up, socks another kid in the face, thus creating a domino effect getting everyone withing a fifteen foot radius involved in a mosh pit.

Slam Dancing- Cool when done by an established dominant, but not when done by a AFEK trying to be cool. You flail your arms around like a crazy person, and sometimes stand and act like your stabbing someone multiple times, hitting kids in the face left and right.

Nu Metal- Ass Fags making Non-Music. There is no such thing as a Nu Metal, or even a Metal mosh pit. The head bangers head bang, but do not mosh. because moshing is for punks, we started it.

The ultimate way to show your love for your loud, pounding music taste. Controlled violence. The thing about the Mosh Pit is NOONE will take offence at you whacking them in the face...(I personally congradulate those that get a good shot in) there are different type of "pits" you can participate in, here are a few.

Closed Pit: Tight, hard to move and hard to breathe. A closed pit will usually happen during popular heavy songs like Slipknot - Duality or a S.O.A.D song.

Open Pit: Generally the worst/best you can pick a target and reach them, throw them across the floor punch them, barge them. There's enough room to just dive about punching everyone still causing little offece (Do be prepared to be hit back...a lot)
songs that will get open pits are the less popular but heavy ones.
Motograter music gathers a lot of open pits.

Circle Pit: The larger or stronger Moshers or Metal heads will run around in an empty circle punching those on the outside of the circle and pushing the runner infront until he either leaves or falls to be trodden on. these will happen on most slayer songs.

Slam-dancing Pits: Created by "Wooble" of Wolverhmapton fame. One hand will be behind back at all times (usually holding your beer) and the other one will be swinging side to side, whaloping other slam-dancers and headbanging to yourself.
Lamb Of God - Now Y...

a thing that takes place at metal concerts in which people basically kick the living shit out of each other.

Mosh pits are when a group of headbangers or moshers or anything like that start to fight amongst them selfs.

This usaly includes:
Throwing your arms around to protect your own personal space.
Teaming up with a friend and spinning around so that you can both go flying into the crowd that soon gathers around.
Frantic pushing and shoving to get into the middle of the pit and join in with the singing(but more likly screaming) of the lyrics.

I have encountered three forms of mosh pits, grudge pits(where you pick a foe and dont stop fighting with them untill the music carms down), Open pits(where you can actually move and possibly hit other people), and closed pits(in these you can move very little)

Getting beat up in a fun way; people that like punk rock music run around in a circle and crash into each other for fun.

Formed by Metalheads/Rockers/Moshers/Punks as a form of dance and can (sometimes) be used as a highly effective death sentence for Chavs

The area near the front of the stage at punk rock and metal concerts where fans will run into each other continously. This is also known as slamdancing. It is not uncommon for people to shove their friends into the pit. Normally, the pit isn't very dangerous, and most will follow the rules of a friendly pit. For example, if someone falls down in the pit, the other moshers are expected to pick them up and get them out of harms way.

There are also variatons on the mosh pit, including circle pits, and the wall of death.
