The expression "laugh, scream, etc. your head off" means to do something with a lot of energy and enthusiasm. For example, if you're watching a really funny movie and you're laughing so hard that your head hurts, you could say that you're laughing your head off. Or if you're at a scary haunted house and you scream so loud that your throat hurts, you could say that you're screaming your head off. It's just a way to describe doing something intensely.
