A
phrase invoked, with or without the
subsequent touching of the
index finger to
the nose, when one is in a group and wishes to
disavow responsibility for something. The last person seen not touching
his or her nose is
it.
Of course, if everyone in the group does this nigh simultaneously, the only fair way to resolve it is for everyone to touch their right earlobes as quickly as possible.
In the event of an earlobe touching tie, responsibility shall be determined by good, old-fashioned rock, paper, scissors.
