Computer confetti
<jargon> (Or "chad") A common term for punched-card chad, which, however, does not make good confetti, 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.
