swinging-door chad

plural swinging-door chads

1. chad with two corners detached

   My discovery of the chad in all its permutations — the dimpled chad, the hanging chad, the penciled chad, the pregnant chad, the swinging-door chad, the tri-chad, the incomplete detached chad, the trapdoor chad, the nondetached chad - opened up a whole new world.

   In brief: a "pregnant" or "dimpled chad" was one bearing an indentation left by the voter but which had not become detached at any of its corners. Those would not be counted as votes. Other chads with one corner, two corners or three corners detached - "hanging door", "swinging door" and "tri-corner" chads respectively - would be counted.
