I'm straight edge, but I don't wear the X on my hand that much.

Coined by Ian Mackaye of the band Minor Threat.
It always means
smokes drinks drugs or promiscious sex.
Sometimes it means not consuming meat and caffiene, it varies.
It's about strength as a person.
Usually kids take it too far and can be real asshats about it.
Most edge kids break edge/sell out by the end of their teens.
hatexedgers act like jerks to non-edgers because they are insecure about themselves and think labels like vegan and straight edge make them a better person.

A philosophy originated in the early 80's in the US punk rock community which defines a punk who does not use drugs (either legal or illegal). The name came from a song from the band Minor Threat that briefly described what was understood as the straight edge way of life. In the early 90's "straight edge" started to be viewed as vegetarian, contrary to promiscuous sex and even religious which is not true despite the attitude of certain groups inside the community who can be held responsible for such image.
A:I am a straight edge / I am a straight edger

B:What does that say about you?

A: It means I am a member of the punk rock community who does not use drugs and choose to define myself as a straight edge

B: Is it true that you guys are all vegetarian, avoid promiscuous sex andhave connections with christian and hindu religions?

A: I think most straight edgers are either vegan or vegetarian but I have not met many who would avoid sex for moral reasons and many of us are atheists.

keeping a clear mind and a clean body.

refusal to use drugs, drink, smoke or have promiscuous sex. a phrase originally from a minor threat song glorifying the lifestyle.
I am proud to be set apart from the crowd, based on my lifestyle choices. I am clean, I am cohereant, I am straight edge.

Purity of body and mind. Alternative to being a crutch-lover, which is what the "in" thing nowadays is to be.
sXe is a way of life, thinking, and a major commitment. Mainly, it is having a clear mind and clear body.

given proper identity from hardcore punk band minor threat, straight edge will not take drugs or alcohol.
also often known to listen to "hardcore" music. but not actual original hardcore such as the cro-mags, black flag, the germs etc. hardcore used by these fuck wit straight edgers is just screaming and bands who think they are tough just because they grew up on the streets
im so straight edge i will go to the pub and drink coca cola.

im going to a gig to punch thin air and do spinning kicks.
