Somebody who doen't smoke, drink excessively or have sex with someone if it doesn't mean anything to them.
Lots of people think it means you don't drink at all but that's not true, people who are straight-edge do get drunk, they just don't LIVE for getting drunk, they don't go out every weekend and drink for the sake of drinking just because everyone else is.

Started by Ian Mackaye, the lead singer of Minor Threat. Edge kids wore X's on thier hands. The rules of Straight Edge was that you did not have one night stands, you did not drink any form of alcohol, you did not do drugs and you did not smoke. The earlier skinheads were mostly Straight Edge.
Minor Threat was a Straight Edge band. Ian Mackaye amazingly also had a strong part in the creation of emo, except in his time itwas called emocore.

Straight edge is a real and life long dedication. people say that they're straight edge when they don't even know what it means. it's no drugs, no alcohol, and no casual sex, true. b ut it's not just that. it's no impurities are to enter your body, period. it means you won't poison your body or mind at all. not jus until your 18, or 21, or married. YOUR WHOLE LIFE. all the "scene" and "emo" wannabe-s claim to be straight edge, but they can't even define it. they just to be cool. they realy need to research. seriously.

A way of living involving no drugs, alcohol, or premicious sex. This term originally came from a 1980's hardcore band named Minor Threat. They wrote a song called "Straight Edge" (you wouldnt guess). Most people don't know why they were ACTUALLY straight edge. As many people know, the 1980's hardcore was a group of people who just wanted to be different than everyone else. At this time period, all the kids were smoking weed, drinking beer and doing all that shit. These hardcore kids did it to be different. In today's society, most straight edge kids don't know about this and are just straight edge to be cool.
Back in the day, Minor Threat was a straight edge hardcore band.
