Someone who is not, under the influence of drugs and alcohol.

Straight edge was invented by a song from the band Minor Threat in the early 80's. It was all started by one line in a 45 second song, I've got the straight edge. It was invented in Washington DC and was brought up to Boston by a guy named Al Bareal he invented hardline. Straight edge has three simple rules no drinking, no drugs, and no smoking. Hardline is much like straight edge but has more rules than just no drinking, no smoking, and no drugs. No caffine, have to be a vegetarian or vegan, no sex unless it's procreation, no imported chocolate, no porn, no masterbating are some of the other rules. There are two types of straight edge lifestyles the positive an the militant. Boston is known for it's militant type edge, Boston Beatdown. Straight Edge is a lifestyle not a label. It is a new generation. Here is the real history and def of straight edge.

a person who doesn't drink, smoke or anything bad.
and yet they have a repetation for being 'bad asses'
you know that every STRAIGHT EDGE kid has smoked, they
are more emo

Once affiliated with the conservative element of the punk movement (against drugs, alcohol and casual sex, extremist elements were anti-abortion and sometimes violent) in the 1980s. Now, however, the meaning can also include people who distinguish themselves from their peer group by abstaining from drugs and alcohol by personal choice rather than by affiliation with the punk subculture ideology.

A movement started in the early 80's from the hardcore punk scene. Basically it means to be drug free.

One major note: you can't be edge if you have more than three bedrooms in your house.

Alright, lemme clear some of this out for you guys. Straight Edge is just a matter of opinion. We are a group of people that would rather go to a hardcore show than get shitfaced at some lame ass club. As far as smoking cigarettes goes, any self-respecting person shouldn't buy them because you're paying to destroy your own lungs. And drugs, well that's the touchy subject. Most of us choose to abstain from drugs because of what they've done in our personal life.

But, before you call us out and say we're queers for out beliefs. Just remember, you're the people that are wasting your time bad-mouthing a group of people on the internet.
(A kid who says he's straight edge and then goes and smokes and drinks is not, I repeat not straight edge. Believe me, we hate those guys just as much as you do.)

sXe - the philosophy of being straight edge. No drugs, drink or casual sex. Often associated with the hXc genre. Straight edge individuals are often seen rockin tight jeans and nike dunks.
