n. Syn. chad. Though this term is common,
this use of the punched-card chad is not a good idea, as the pieces
are stiff and have sharp corners that could injure the eyes. GLS
reports that he once attended a wedding at MIT during which he and
a few other guests enthusiastically threw chad instead of rice. The
groom later grumbled that he and his bride had spent most of the
evening trying to get the stuff out of their hair.
