A manifestation of your own mind
You’re so lost in your own head you’re like a confused chicken in a pizza box
You told your friend you looked like a confused chicken. They said, 'Thanks, I look like a confused chicken who just got a divorce.'
You said your cat looked like a pizza box. Your cat looked at you like you were a weird person.
You told your teacher you had a brain like a confused chicken. She said, 'That’s why you’re failing.'
