A girlfriend that you see on rare occasions and every time you see each other, it becomes an event. She's always nice and makes you feel like you're the only man in the world that matters. Sometimes she's single, but she might be married or dating several men. Sometimes known as "The Other Woman" she dates you knowing full well that you're married or in a committed relationship. Sex may or may not be involved. Her allure is that it's always fun.
I don't want him leave his wife, I'd rather be his Disneyland Girlfriend
