A young female horse who hasn't yet learned the word 'no' has limits.
means A young female horse, typically under the age of four and not yet fully grown — and, by old slang, a spirited young woman.
from From Old Norse 'fylja,' a female foal, a cousin of 'foal' itself and of the Old English word for young horse. The horse sense came first; the playful, sometimes patronizing use for a lively young woman is a much later figurative gallop off the same root.
