Grab the empty beer bottle
From Create Your Own Story
You scoop up the long-handle forty-ounce bottle. You keep backing up as they approach you. "What's wrong with you guys, what happend?" you ask them, but they just moan and bring up their arms to try and grab you. With that college hazing ending with a student's beheading in the news a couple of weeks ago this is just too weird. You begin the freak out.
You smash the bottle into the closest one's face You drive to get around them to run out into the street
