The Coed and the Zombie Stoner (2014)

Rather than a pesky sorority event, the heroine is a female loser who falls in love with a zombie man and takes him around the market. The zombie man bit each other after being provoked, and then the wave of dead bodies broke out on campus. On the way to escape, the female loser found that marijuana has the ability to cure zombies, so all the culprits were perfectly transformed into heroic female losers who saved people and water and fire.
