mad pet
When you're so scared you're like a chicken with its head cut off. You can't think straight and you're just running away.
I was mad pet when I saw the spider. I screamed and ran out of the room.
The dog chased me and I was mad pet. I hid under the table like a coward.
I was mad pet when I failed the test. I ran out of the classroom like I was being chased by wolves.
