A flirtatious look is a way of expressing romantic or sexual interest in someone without using words. It can involve a WINK, OGLE, or a glance with a 'glad eye'. A WINK is a quick closing and opening of one eye, usually to indicate a joke or secret understanding. Ogling is a prolonged stare, often with a leering expression. A glad eye is a lingering look, usually with a smile, that conveys admiration or attraction.
