Rosie at the fair

To be "rosie at the fair" is to lead on a boy who has no hope usually at a big public event.

Girl one: have you seen sarah flirting with mike??? Girl two: I know she's rosie at the fair :P. Girl one: he doesn't stand a chance with her, and at this public event! Girl two: it's just cruel
