A mixture of being shit scared and petrified
"Man, I am downright shitrified of that fucking finance class"
A form of elaborate execution in which someone shits inside the victims mouth and forces him to swallow it.
I shit in his mouth and he swallowed that bitch. He died the next day.
When something you witness is so shitty, it leaves you petrified from its shitness.
"This game leaves me shitrified, I hope no one else plays it."
