[popularized by Johnny Hart's comic
strip "B.C." but the word apparently predates that] 1. To
clear the state of a wedged device and restart it. More severe
than `to frob' (sense 2). 2. [TMRC] To cut, sever, smash,
or similarly disable. 3. The sound made by many 3.5-inch diskette
drives. In particular, the microfloppies on a Commodore Amiga go
"grink, gronk".
