The face someone makes when they are about to sneeze.
Jane: I went out with John last night... He's cute but he kept making this zombieface. I think he has terrets.
Sue: Maybe he had to sneeze.
Jane: He should have noseturbated
Bob: How did the interview go?
John: Horrible. I had to sneeze so bad I zombiefaced through half the interview. And to make matters worse, I sneezed so hard that I blew boogers all over the desk.
Bob: Should have noseturbated
before you went in.
