According to witnesses, the confrontation began after another driver would not move her car.
The incident escalated as the two began arguing, before the seemingly carnivorous attacker began biting the other woman non-stop.
"She was like, 'Aaargh, aargh,' and she just kept biting her," the victim's boyfriend explained. "[She] kept biting her and my girlfriend was like, 'Help. Help.'"
"I don't know why she would bite me," the victim said, seemingly stunned.
Asking that she not be named, she remarked: "I don't understand why anybody would bite anyone...unless you were hungry, and I don't really taste that good. I hope not."
Police identified the suspect as 32-year-old Sara Gillian of San Francisco, charging her with assault with a deadly weapon.
KTVU interviewed the victim, and while they say it is not uncommon to hear of escalated parking disputes in California-- the violent biting is something they've certainly never seen before.
