There is another folk tradition which may use a variation "Rabbit", "Bunny", "I hate/love Grey Rabbits" or "White Rabbit" to ward off smoke that the wind is directing into your face when gathered around a campfire [REF].
As with all folklore, its truth is made evident even in its only occasional fulfillment: should the wind then appear to change direction, others will interpret the use of such an expression as evidence of its effectiveness and will then tend to adopt and repeat its use.
