Facial Clench
A Facial Clench is the worst thing you can say to a zombie when you’re about to get bit
'I'm gonna Facial Clench you so hard you'll wish you were dead.', Mark, during a zombie ambush
'Facial Clench! I'm not scared of you!', Lisa, trying to sound tough
'Facial Clench! You're gonna regret this!', Tom, who was already bitten
