This one is a good substitute for a hex, when your fear or anger tempts you in that direction:
“Blood turn black and flesh turn blue,
I will curse if you force me to.
By the left hand and the unclean food,
I’ll curse your eyes, I’ll curse your lies,
I’ll call down a plague of flies.
Blood go black and flesh go blue,
Evil from me and back to you
My soul clean and yours on fire,
You screwed with a witch you get burned, liar! “
