That last piece of food that a group, i.e. 3 or more peole are partaking in. Generally the last piece of pizza. Going back to the late 80's, the Blair Piece was first discovered when it was observed that the last piece of any food was consumed by Blair.
'I was going to have another piece of pizza but, Tommy already grapped the Blair Piece. I guess I am S.O.L."
