When someone comments on a girl then someone else says 'tell her Tuesday' they have to tell that girl what they said about her. Can only happen on Tuesday.
Person 1 - That (girl) has a really nice ass!
Person 2 - Tell her Tuesday
Person 1 to the girl - You have a really nice ass
Person 2 - Tell her Tuesday
Person 1 to the girl - You have a really nice ass
