Ah yup its basically a descending count outloud to pile on the pressure to approach, it makes AA and pickiness over 'type' etc crazily diminish. When it gets to '6, 5, 4...' I'd run up to a three-set of models just to open within the time limit. There doesnt even need to be a punishment for not opening. Often we do '2 and a half, 2, 1.8, 1.6, 1.4' etc to be nice. U can do social forfeit dares like lying in the street or standing in a weird position for 2minutes or shouting and starjumps etc if u want. Sometimes a friendly punch on the arm. ONly warning is a tendency to eject from good sets by accident bcos of thinking 'I;v done my approach now, its that guy;s turn' Then later 'Shit I quite liked her actually..'
