Any individual who has teeth that are so "jacked up" it looks as though that person has been chewing on rocks.
"That girl last night had the most fucked up teeth I have ever seen."
"Yeah, she was a definite rock biter."

A person who chews, eats or bites rocks for some unknown reason leaving their teeth broken, chipped and crooked therefore resembling dolphin teeth.
CFCC's english 111 teacher, Miss Hemingway eats mad rocks. Gabby Lyons loves to eat rocks but all that rock biting has left her with dolphin teeth. Too bad she's such a rock biter.
