Zombieland

Two months have passed since a strain of mad cow disease mutated into "mad person disease" that became "mad zombie disease" which overran the entire United States, turning American people into vicious zombies. Survivors of the zombie epidemic have learned that it is best not to grow attached to other survivors because they could die at any moment, so many have taken to using their city of origin as nicknames. Unaffected college student Columbus is making his way from his college dorm in Austin, Texas, to Columbus, Ohio, to see whether his parents are still alive. He encounters Tallahassee, another survivor, who is particularly violent in killing zombies. Though he doesn't appear to be sociable, Tallahassee reluctantly allows Columbus to travel with him. Tallahassee mentions he misses his puppy that was killed by zombies, as well as his affinity for Twinkies, which he actively tries to find.
