Winking Girl

In some cultures it is often a sexual interest, or flirtatious manner, during momentary eye contact. This is often followed by a smile, and usually a smile from the receiver, if it is accepted/approved, or combined with blushing if they are embarrassed. A smile from the receiver sometimes—but not always—indicates (sexual) interest in the winker.
• Double wink ("wink wink")
Like a single wink but more emphatic, two winks in a row may be used by the sender as a subtle way to imply that something said by the sender, immediately beforehand, was "sneaky", "tricky", "misleading", or "untrue" to the receiver. In English-speaking countries, this has also given rise to the expression of vocally saying "wink wink" while winking, or sometimes while not even winking at all - in this case, the sender is not communicating the "trickiness" of his words to a third party, but to the receiver, and is thus signalling that his words should not be taken literally but as a hint or euphemism.
