1. Maryline is a woman who sets her own definition - a woman of power, principled, individualistic, self-conscious, eccentric, and creative. When in love, an incorrigible romantic, a miserable poet; in a fit of fury, her voice echoed like a damning curse of an ancient goddess; when happy, she strolls in pride and everything else considered nuisance by any standard, looks like a harmless ant.
2. Someone who holds and practices a very sophisticated, transcendental view towards life. Her way of life is a matter of complete freedom within the boundary that she won't hurt others nor set anyone in a cage. Within her circle, you won't feel the circle: you'd feel unconstrained and at ease being yourself.
3. A divine name. The spelling "Maryline" is a rare variation of "Marilyn", elaborated from "Mary" which means Star of the Sea (latin: Stella Maris) - an ancient title of the Virgin Mary.
Example: I know what kind of person this is: she is a complete Maryline!
