Winking Girl

West African parents may wink to signal children to leave the room, especially when there is a guest, or another adult coming in. It is considered rude for children to stay in a room where adults or elders want to have a conversation, and so winking is used as a more discreet way to tell the children to leave the room. Parents also try not to embarrass themselves in front of guests, because their children do not understand immediately when it is time to leave the room.

• In the famous Monty Python sketch Nudge Nudge, a younger man slyly asks an older gentleman about sex through innuendo, reiterating the phrase "nudge nudge wink wink" after his questions in an attempt to indicate that his innocent-sounding questions are intended to be double entendres, i.e., of a sexual nature.
