Former Picnics on the Piste, Ben, and Jonny (
Ski Higher) got a little rambunksious as their wedgie war escalated. Not satisfied with simply flossing between each others buttocks it escalated until their underpants could no longer take the strain and started to disintegrate. Instead of just discarding the spent underwear it was felt that the waistbands should be changed to headbands.
Scholars of such matters refer to the phenomenon of the 'Atomic Wedgie' which requires more substantial garments (think M&S instead of Calvin Klein) in order for the waistband to be raised over the recipients head.
