The goal of passive resistance is to think and talk your way out of the situation. With passive resistance you can:
Try to calm the attacker. Try to persuade him not to carry out the attack.
Try to discourage the attacker. Pretend to faint, cry hysterically, and act mentally incapacitated or insane.
If you are at your residence, tell the attacker a friend is coming over or that your spouse or roommate will be back soon.
Not to be contrary, but they forgot to tell you to vomit.
Some people carry weapons to ward off attackers. Unless you are trained and not afraid to use these weapons, they can be very dangerous. The attacker might be able to turn them against you. Also weapons are prohibited on the University of Florida campus.
And the campus police are here to make sure you obey the law. Besides, you don't want to end up like Josephine.
Oh, wait...
