Straight Edge
If you are ready to go

I had a black x-mark on the back of my hand
I was playing guitar
And singing a song on the stage
I was straight edge
I never smoke
I never use drugs
I never sleep with boys without love
I was at south by south west
I ate death metal pizza so many times
I missed metallica show
That night when I was straight edge
However
On the stage
Song on the stage
I saw from the window
The lady was getting a tattoo
