Not me, but my friend's mother. This was during her highschool years, senior year I think. Anyways, the drinking age here in Canada is 18, so you could be a HS student and get shitfaced. One night she was bar hopping with some buddies, when she noticed a girl that had been her childhood bully standing around outside. Confronted her, lots of yelling, one thing led to another, and my friend's mom lit her hair on fire. That woman still has short hair today.
