Hjjjälp! Vad fasiken heter det på engelska?

"Several American subscribers have told me that they remember the term being used among children for head lice back in the 1920s. Even in the 1950s and 1960s, the word was still common in this literal sense (and, of course, it's still known as such). There was also the cootie catcher, a folded paper shape that you could use to pretend you had discovered cooties on a schoolmate."
